Forgot a couple of art assets, so added them to the files

Added 131 art files

Added a lot of Orks to the game - currently most don't have abilities, but its preperation for later.

Please note: some art is not fully finished and may be too dark, or need tweaking, the mek is one example.

Lots of little bits and new stuff, including work on snotlings, spores, orks, hunger meters, kill meters, damage, health, range, defense stats. Evolution system.
Basically the framework for what comes next.

Quick bug fix, still learning linux
