v0.3

Just doing some quick bug fixes that come with the joys of early access.

Fixed a bug in regards to the fence on the Surface level, where the hitbox of the fence was too high and players could not jump over it.

Fixed the texture on the columns in the trainyard.

Allosaurus now gives 50XP when killed vs 25.
Heavy Soldiers now give 25xp when killed.

Fixed some other minor hitbox errors.
C4 is default key mapped to G now.

Added a new floor model to the main menu.
