Message:

merged usability branch back to trunk

incomplete summary of the changes in this branch:

• enhanced keyboard navigation in GUIs
• implemented new graphics menu and changeable window size at runtime
• added developer mode
• HUD shows if game is paused, game pauses if ingame menu is opened
• removed a few obsolete commands and hid some that are more for internal use
• numpad works in console and gui
• faster loading of level info
• enhanced usage of compositors (Shader class)
• improved camera handling, configurable FOV and aspect ratio
