Improved AI navigation for more performance in Ai combat and fixed some stuckidle nodes around C.P. Echo.

Changelist:

-Opened secondary path from Alpha to Bravo
-Removed maintenance doors closing after capturing Foxtrot.
-Minor map fixes and improvements.

Fixed ED_Alloc crash when playing with 32 bots

Reduced entity count so the map should work fine with higher bot count.

I hope it works fine now :)
