b8c3264019 fix(main): Handle errors & logic when templating to directory
This does several changes to the new "template to directory" feature
introduced in the previous commit:

1. Errors are now "handled". In classic Go-style, it is of course all
   too easy to do absolutely nothing with errors, but we can't have
   that. I'm onto you, Renee French's husband!

2. Resource sets containing similarly named files are now templated
   correctly by prepending the resource set name to the filename.

3. In the same vein as the previous point, nested resource sets are
   now also output correctly by replacing slashes (`/`) with
   dashes (`-`) to guarantee that the output files are a flat list.

Some minor cosmetic fixes have also been applied.

84dcc294bf feat(main): Support output directories in template function.
This introduces a new command line flag `--output` (or `-o` for short)
which makes it possible to template all specified resource sets into a
folder (instead of to stdout) when using `kontemplate template`.

3ea3bed7ac fix(templater): add baseDir to gitHead cmd so that directory is overwritten
This makes it so that when gitHead is called in a template the git hash
that is returned is the hash of the folder containing the template, not
the hash of the folder where kontemplate is called.

e1c2c19330 feat(templater) Add a template function to insert surrounding repo's Git hash
A template function has been added that allows one to template the
Git hash of the surrounding repo. This is useful to be able to inspect the
deployment revision of an object in Kubernetes.

3aa2cb8d3e refactor: Remove old error handling library
Removes the old error handling library and switches to plain
fmt.Errorf calls.

There are several reasons for this:

* There are no useful types or handling here anyways, so output format
  is the only priority.
* Users don't care about getting stacktraces.
* My emotional wellbeing.

Fin de siècle.

7bbc3cc033 Version 1.3.0
This release comes with minor usability improvements and features.

* A new 'lookupIPAddr' template function is available for resolving
  DNS A records in templates. Thanks to @landro for the pull request!

* Handling of "non-standard" resource set structures has been improved
  to result in better error messages and behaviour in several places.

Release binaries are signed with GPG key `66F505681DB8F43B` which is
verified on my Github profile.

--------------

Note: This is the last Kontemplate release that will be written in Go.

Rob Pike's art project has proven its point but I believe it is
ethically questionable and morally indefensible to continue on this
path.

You can track #72 for the Rust-rewrite of Kontemplate.

9cffd3d1d4 refactor templater: Add explicit note about empty-rs warnings
Due to an interesting combination of an error not being handled and Go
initialising everything with what it thinks should be the default,
non-existent resource sets have been gracefully handled already.

This makes this accidental fix explicit.

b20bc5f57a fix templater: Don't template default.yml files
After the change from #84 default variable files with the '.yml'
extension got templated as resource set templates accidentally.

This resolves the issue by moving the list reserved default file names
to a common place and reusing it in both the templater and context pkg.

This fixes #85

variables, too.

Version 1.2.0
This release comes with some new features, usability improvements and
a better build & release process.

Features:

* Documentation has been improved significantly, check out the new
  [README][] and follow the links within!
* Extra variables can now be loaded from files on disk. Simply specify
  a list of YAML/JSON files under the 'import' key in your cluster
  context file. Check out #66 for details!
* Resource set paths can now be overridden by users. By default it is
  assumed that the path to a resource set is the same as its name,
  however this is now user-controllable.
  This means the same resource set can be included multiple times
  under different names, for easier including/excluding. See #71 for
  details!
* Kontemplate is currently getting a website that is under construction
  at [kontemplate.works][] - feel free to check it out and
  [give feedback][]!

Fixes:

* Windows release binaries now have the correct filename
* Several potential warning and error messages have been improved

Release binaries are signed with GPG key `66F505681DB8F43B` which is
verified on my Github profile.

e8cfa9c119 refactor build: Keep GPG-signatures outside of tarballs
Instead of signing the binary and adding the signature in the release
tarball, keep the GPG-signatures *outside* of the tarball.

This makes it easier to use the built-in GPG-signature verification
features of package managers such as pacman.

7607f6dc0f feat context: Allow overriding resource set paths
Instead of always inferring the path at which files in a resource set
are located, let users override the path by specifying a `path` field.

This makes it possible to add the same resource set multiple times
with different values while still keeping distinct names for
addressability (for example when using include/exclude).
