Bot hints

Thing type 2004, adds a map-defined point for bots to gravitate towards or away from.
Angle: Changes radius, defaults to a 32 radius (or 64x64 area) without.
Ambush: When off, makes bots steer towards. When on, makes bots steer away.
Parameter: Changes how much the bot steers away/towards this point. If 0, defaults to 2.

(also, made bots ignore strong offroad if they could take a shortcut)
