Quaternion: Removed operator- since it doesn't seem geometrically
sensible for rotation-quaternions. Added ToAxisAngle but don't actually
use it anywhere.
GameView: Changed unit-view to look slightly more correct.
This was SVN commit r3201.
ObjectBase: removed support for old actor format
Various: reduced sometimes-unnecessary header inclusions
Atlas: slightly nicer tool and message systems
This was SVN commit r2816.
