- defined a constant for the crosshair menu entry's index to get a direct

reference out of the function code.
- Fixed: The BrainExplosions should not perform any collision detection. To
  achieve this their Damage value must be set to 0 when being spawned.
- Added a safety check to savegame versioning so that an invalid revision
  (reported as 0) will be handled without breaking savegame compatibility.
