Fixes between beta1b and beta2:

- Rocket launcher reports ammunition correctly, instead of being stuck at
  50 or 100. Fixes Bug #243.
- Mouse input now "grabs" correctly when going from full screen to windowed
  and back. Fixes Bug #382.
- Viewpoint shouldn't "jump" when returning from console/menus/chat/etc
  anymore. Fixes Bug #282.
- Launcher script should respect symlinks better. Fixes Bug #280.
- Beta expirations updated for another month. Fixes Bug #361.

The game is STILL not beatable by default. This is a bug. You can "cheat" to
 kill the last boss when you are sick of shooting at him, though. Pull down
 the console and type:

 /cht_bKillFinalBoss = 1;

(The '/' and ';' are necessary.) This will kill the boss and trigger the
 endgame cinematic.

This bug actually breaks the opening cinematic of The Second Encounter, so
 it's important to fix it, cheat or not. But not for this patch.

Have fun!
