Merge aszlig/nixgames into vuizvui

This is a subtree merge of the full nixgames repository including
history. Right now it isn't linked to vuizvui at all but we're going to
do that very soon.

The reason why I'm merging both repositories together is that it's
easier for me to manage updates and also facilitate contributions by
people from the OpenLab.

Another reason to merge it is that we can write more generic functions
for building both, the games and the rest.

Right now the licensing is still the Apache License version 2.0, but
we're going to change it to the vuizvui license as well.
