296f73a4d6 Display messages in the order they were sent
Rather than displaying messages most-recent-first in the message box,
display them most-recent-last (which feels more natural)

ce3730ba3a Small chance of hurting self when punching
When attacking monsters with bare fists, there is a small chance (8%,

9ec51e5123 Entities inside a wall can't see anything
The test for "one step in each cardinal direction is always visible" was
giving a false-negative for an entity at the same position as a wall -
not only is this something that would ostensibly never happen, it's also
completely reasonable to assume that someone stuck in a wall (due to a
bad teleport perhaps?) wouldn't be able to see anything, on account of
their head being INSIDE A WALL.

2320cfa8cd Use open circles to generate filled circles
Rather than leaning on rasterific to generate filled circles for us,
instead start with an open circle, then fill it by scanning line-by-line
and filling in points that are "inside" of the circle, based on keeping
track with a boolean. Also adds a couple of helper functions for
displaying these kinda "boolean graphics" things we're passing around,
as sets of points.

22b7a9be84 Drop Rasterific for non-filled circles
Rasterific appears to generate some pretty surprising, if  not
completely wrong, circles at especially low sizes - this was resulting
in unexpected behavior with vision calculation, including the character
never being able to see directly to the left of them, among other
things. This moves back to the old midpoint circle algorithm I pulled
off of rosetta code, but only for the non-filled circle. The filled
circle is still using the wonky algorithm for now, but at some point I'd
love to refactor it such that empty circles are eg always a subset of
non-filled circles.

1265155ae4 Don't run initEvent when loading the game
Rather than having a single sentWelcome boolean, avoid running the
initEvent entirely when loading an already-initialized game. Among other
things, this stops us from re-generating a level and then merging it
with the existing one when the game is loaded (oops).

69ccf3a77d Fix argument order to drawEntities
I had swapped the order of isVisible and isRevealed, which was causing
not-currently-visible gormlaks to still be rendered.

25a1c5ade3 Factor out an EntityAttributes type
Factor out a new EntityAttributes type from some of the methods of the
Entity class, to avoid the proliferation of 1-argument boolean methods
on the entity class that always have to be forwarded through the Entity
instance for SomeEntity if they have defaults (forgetting to do which
has wasted tons of my time up to this point). Currently blocksVision,
blocksObject, and collision are all in there.

782d3880c8 Block doors being closed on gormlaks
Prevent closing doors when there's a gormlak or other entity with the
blocksObject attribute set to true on the same tile. There's a message
sent here which is grammatically incorrect - it says "The a gormlak
blocks the door" - should fix that later.

7082a4088b Store revealed positions on the level itself
This was a bit of an oversight initially - we should be storing the
positions that the character has seen *on the level*, rather than on the
entire game state, for obvious reasons. This introduces a GameLevel
record, which has this field, the entities, and also the up staircase
position, which we can *also* use to position the character after going
down to a level we've already visited.

New levels need to go at the *end* of the list of levels, not the
beginning - otherwise we jump to the proper position on the new level
but the current level stays the same (oops).

d62aba218d Switch to DelaunayTriangulation.Naive
Per https://github.com/noinia/hgeometry/issues/28, occasionally
DelaunayTriangulation.DivideAndConquer loops infinitely - in this case,
I was able to consistently use the seed 127624940715530481, to generate
a dungeon which had the following room centroids:

    [ Point2 [38.5,3.5] :+ 0
    , Point2 [67.0,33.0] :+ 1
    , Point2 [46.0,45.5] :+ 2
    , Point2 [55.5,42.0] :+ 3
    , Point2 [36.0,25.0] :+ 4
    , Point2 [76.5,12.0] :+ 5
    , Point2 [29.0,26.5] :+ 6
    , Point2 [55.0,10.5] :+ 7
    ]

and cause delaunay triangulation to loop indefinitely (or at least
longer than I cared to wait for). Given the size of our graphs switching
to naive generation should be fine performance-wise, and avoids the
infinite loop.

0f79a06733 Add staircases, and moving between levels

6b0bab0e85 Add support for multiple levels
Add a data structure, based on the zipper comonad, which provides
support for multiple levels, each of which is its own entity map. The
current level is provided by coreturn, which the `entities` lens has
been updated to use. Nothing currently supports going up or down levels
yet - that's coming next.

84f32efad4 Track entity collision in the Entity class
Rather than having a single function in the Game.Lenses module for
determining what collision type if any an entity has, track it in the
Entity typeclass itself. This is both more extensible and a better
separation of concerns and gets rid of one of the two needs for a
circular import. Yay!

As part of this, I realized nothing was being done to prevent doors from
being placed on tiles that already had walls (since now that was
properly causing a collision!) so I've fixed that as well.

1b88921bc3 Decouple Gormlak AI from creatures
Decouple the definition of the Gormlak AI from the creature type itself
using generic lenses and a "HasVisionRadius" typeclass, to begin to
untangle the hs-boot web of circular dependencies. This
actually *increases* the number of hs-boot files from 1 to 2, but both
of the source imports that use them are single-instance (unlike gormlak
AI which I would expect to grow linearly with the growth of the game),
plus at least one should be able to go away once we remove collision
from the game lenses module and move it into something defined in the
entity class itself.

5c5aa14a3d Don't render moving entities that aren't visible
When the character walks away from or around the corner from entities
that move such that they're no longer visible, stop rendering them.
Still render static entities like walls, doors, and items though. This
prevents entities walking into a "revealed position" after the
character's left being visible despite not being in a line of sight any
more.

ffc8e793d5 Prompt before overwriting files when saving
When saving the game to a file that already exists, prompt for whether
or not to overwrite the file.

Since this was the first instance of a prompt triggered by another
prompt, this also had to do a minor fix to swap the order of completing
the prompt and clearing it, so that we don't submit the prompt and then
immediately clear it.

e76567b9e7 Add dungeon level generation
Add a dungeon level generator, which:

1. generates an infinite sequence of rectangular rooms within the
   dimensions of the level
2. removes any duplicates from that sequence
3. Generates a graph from the delaunay triangulation of the centerpoints
   of those rooms
4. Generates the minimum-spanning-tree of that delaunay triangulation,
   with weights given by line length in points
5. Adds back a subset (default 10-15%) of edges from the delaunay
   triangulation to the graph
6. Uses the resulting graph to draw corridors between the rooms, using a
   random point on the near edge of each room to pick the points of the
   corridors

32421916e0 Update the vision every time we step the game
Recalculate the character's lines of sight every time we step the game,
rather than just every time the character *moves*. I had originally
thought this was a non-contiguous lines-of-sight bug - which there's a
test disproving - but it actually turned out to be that actions like
eating or attacking would step the game forward (thus moving gormlaks)
without re-calculating the positions visible to the character.

052bc8455a Add a drop command
Add a drop command, bound to 'd', which prompts the character for an
item in their inventory, removes it from the inventory, and places it on
the ground. Along the way I had to fix a bug in the
`EntityMap.atPosition` lens, which was always appending to the existing
entities at the position on set, without removing the entities that were
already there - the rabbit hole of quickchecking the lens laws here also
lead to replacing the target of this lens with a newtype called
`VectorBag`, which ignores order (since the entitymap makes no
guarantees about order of entities at a given position).

8ecefddbd4 Use wielded items to calculate damage
Use whatever items the character has wielded, if any, to calculate the

currently only possible to equip something in the right hand.

though, so this is all unused/untested.

Also, add the ability for items to be "wieldable", which gives specific
descriptions for when attacking with them and also modified damage.
