Version 2 of Last Stand

Changes include:

-- New larger catwalk area between the two guard towers.

-- Pathing rebuilt. Zeds will now also jump down off of catwalk.

-- New floor spawns which are triggered by pushing to the front.

-- Rebalancing of the derate timers for the spawn volumes between the back and the front. The front spawnvolume derate time was unchanged, however I increased the time in the back spawn volumes to encourage more continuous spawn closer to the player and less breaks due to large groups spawning in the back.

-- Spawnvolume size in both front right and left spawn areas increased.

-- Added ammo spawns.

-- Cosmetic touches and enhancements, added dosh bling.


Overall the changes should make the map more difficult.
