A lot of relatively major changes.
	- Added a licence so thats out of the way.
	- Added base abilities to races so that every member of a given race is
capable of the same basic stuff. (A bug in this got a bit out of hand
but it should be all good now.)
	- Made PC setup respect the previous point.
	- Added a dynamic class loading functionality for moddability purposes.
	- Begun work on actually loading and using said mods.
	- Some more work on abitool. (I've forgotten what I did there...)
	- Probably other things I'm forgetting to mention...
