General:
* increased RED's initial spawn time from 6s to 7s
* improved clipping
* added a couple signs since one or two people still tend to get a little confused where to go at times
* added some areaportals to hopefully improve framerates
BLU Spawn:
* started basic artpass
Point A:
* pushed the doorway at the bottom of the ramp forward to make it less spammable
* also made said doorway wider
* added health and ammo to the long flank route
Point B:
* expanded the cart route between Point A and Point B to hopefully make it less spammy and crazy
Point C:
* added some cover to the hallway leading to C
