AnyUnitSize merge: refactoring and cleaning up
These are small scale fixes I've made in AnyUnitSize branch:
- Removed global Quit method. Event manager exits its event loop more gracefully.
- Moved utlities like pcx, unifonts, tinyxml to appropriate folder
cUniFont font;has ben moved to static field inside cUniFont
#include "gameversion.h"from netmessage2.h. It caused massive rebuilds after every git change.
