This is not yet fully functional, but going in the right direction.
Some concepts are introduced:
* There is a light theme (used for blog entry pages) and a dark
theme (used for the homepage itself)
* Entries can be either blog posts, projects or miscellaneous things
that I want to link people to (possibly with a comment)
It might be interesting to add pages that filter to specific types, or
some such, which should be relatively easy to do.
Note that the layouts of entries are not actually done yet.
