Merge pull request aszlig/nixgames#1 from @layus

This adds Unepic to the humblebundle games list and also fixes Bastion,
or at least it *should* fix Bastion.

I have tested Unepic, though I had to fix the download, which I'm going
to commit later.

As for Bastion, at least with the humblebundle fetcher it's not able to
fetch "bastion_linux" (it doesn't even show up), however on my Humble
library I can see the download (maybe it's because I bought this along
with HIB 5).

Nevertheless, it's at least a small step forward and we need to fix
these issues later.
