Stops idle syndicate mobs from destroying surroundings

Adds a variable ('idle_env_destroyer') to all hostile mobs, denoting
whether the mob destroys it's environment while idling or not. Default
value is 0 (no). Syndicate, russian and pirate mobs are affected. Also
prevents aforementioned mobs from suiciding and/or wrecking away mission
environments before the player could see them.

Fixes hostile mobs interpreting 'null' as a valid target and always
being in HOSTILE_ATTACK stance.

The APC's extra Topic() parameter was causing a runtime to occur when you used ..(). Fixed it by removing the parameter and re-arranging the code so it wasn't required. Fixes Issue #1148.
Added comments to the airlock to help prevent this happening in the future.
Made all unsimulated/wall turfs have block_air = 1 instead of only the fakeglass walls
Randmutb will no longer select and mutate RACEBLOCK - mutagen, cloning, radiation-events etc will no longer cause this block to change.

IsBanned() now only processes the key into a ckey once...rather than several times.
