More updates and also the source code

I've decided to make the source code available.    

The license is GNU AGPL v3, but you'll need to accept UEEULA and also to buy some commercial paid content if you want to distribute it in any form. There's about $300 worth of paid commercial content used in the game, but I plan to use less of it in the future as I'll have time to replace it with my own.

My own content source files (mostly Blender, GIMP and Krita) will eventually be available here too under CC BY-SA 4.0 and GNU FDL v1.3.

Also lots of updates happened to the game, so make sure to check it out.
