Random Unit FFA

Changed the following spawns per spawn:
 - Reapers decreased to 2 (from 3).
 - Hydralisks increased to 4 (from 3).
 - Zealots increased to 3 (from 2).
 - Phoenixes decreased to 2 (from 3).
 - Scouts decreased to 2 (from 3).

 - Increased the size of the SCV box to prevent accidental choices.
 - Increased the game's Time Limit to 20 Game Minutes.
 - Forced Alliances - Everyone is an enemy against everyone else. (Need to test to see if it is locked -- Probably is).
 - Changed Kill System to a Kill Point system.  Every spawn will give a total of 8 points and 8 Minerals to the killer should he get all of the spawn.  Zealots are the only exception giving 9 of both total.
 - Added Random Chance for Medics and Science Vessels for all race choices.
 - Changed the Spawn locations to a random choice between 30 different spots.  This will prevent camping.  Medics and Science Vessels however will spawn at the old location so that a defenseless unit does not get spawned in the middle of a battleground.
 - Removed Yamato Cannon (Battlecruiser) and 250mm Strike (Thor).  They are just too powerful for this type of game.
 - Gave Marauders the ability to attack air and increased their damage by 5 (10 more vs. Mechanical)
 - Gave Firebats the ability to attack air and increased their damage to 12 (24 vs. Light).
 - Ghosts no longer have the Sniper Round ability and instead do 50 damage to all Biological Units.  I believe this will make them a whole lot more useful.
