/*

Doors are similar to buttons, but can spawn a fat trigger field around them
to open without a touch, and they link together to form simultanious
double/quad doors.

Door.owner is the master door.  If there is only one door, it points to itself.
If multiple doors, all will point to a single one.

Door.enemy chains from the master door through all doors linked in the chain.
