[Ze_PilOt]

- Team request window is non modal anymore (they don't block the interface).
- Searching bar is non modal too ("searching for attackers"). It's now a progress bar like the matchmaker.
- You can't cancel maps & GW update by typing (cancel button removed)
- News ticker is back.
- Fixed some events causing the game to desync.
- Fixed some events leading to the faction selector popup to come again.
- Fixed some events with shader being requested before compilation (the "programConstant" errors).
