Better base_shutdown.lua

 * Add built-in support for trigger-based buttons (blue_security_trigger/red_security_trigger)
 * Add built-in support for Lua-defined security shutdown length (SECURITY_LENGTH)
 * Add built-in support for turning on/off lights, brushes, trigger_ff_clips, and trigger_hurts
 * Add some helpful team-oriented trigger definitions in base_teamplay.lua
Thats really confusing! Why the heck did they do it that way. Reading that says "opposite team is team is red and blue or red?" what.  I am generally against ternary operators anyway but this takes the biscuit. I feel sorry for any potential map makers / semi-coders trying to decipher this. Are you super tied to this syntax or is there another way of doing this?
