* Options menu video modes glitch fixed (a backport)

* Scores will not be reset to 0 for players whose classes change while the scoreboard is showing
* Hive offset fixed so that less of the hive is sunk under the floor
* Buildable positioning cap-traces are cached, saving CPU
* Buildable cap-traces will not interact with bodies (players and buildables)
* For Aliens holding dodge while jumping will result in a weaker jump
Marauder walljump changes:
* Finds a wall regardless of where player is aiming
* No longer uses direction keys to direct walljump (player is using these to hug the wall!)
* Will direct jump in player's view direction
