Added maps (such as metalworks)

Added the following.

cp_badlands_pro is a copy from cp_badlands
cp_metalworks_rc4 is new
cp_standin_rc1 is a copy of an older cp_standin_b5
All cp_process spawns are copied from _b6
cp_ashville_b6 is new
pl_barnblitz_pro is a copy of pl_barnblitz spawns.

Also cleaned up a few semicolons and alphabetized a little bit (such as moving koth_arctic_b3 up instead of being on the bottom).
