Patch notes

-Got rid of pistols as the survivors sidearm due to being too op

-Dmr's are now more prevalent to allow the infected to pick off the machinegunners more effectively

-Fog has been reduced for now untill 343 allows infected colors to be edited as survivors had too hard of a time seeing the charging infected.

-various other fixes to the terrain to remove random holes.

-Moved the crators up more to provide further cover for the charging infected team.
