/*QUAKED func_door (0 .5 .8) ? START_OPEN x DOOR_DONT_LINK TOGGLE
if two doors touch, they are assumed to be connected and operate as a unit.

TOGGLE causes the door to wait in both the start and end states for a trigger event.

START_OPEN causes the door to move to its destination when spawned, and operate in reverse.
It is used to temporarily or permanently close off an area when triggered (not usefull for
touch or takedamage doors).

"angle"         determines the opening direction
"targetname"	if set, no touch field will be spawned and a remote button or trigger
				field activates the door.
"health"        if set, door must be shot open
"speed"         movement speed (100 default)
"wait"          wait before returning (3 default, -1 = never return)
"lip"           lip remaining at end of move (8 default)
"dmg"           damage to inflict when blocked (2 default)
"sounds"
0)      no sound
1)      stone
2)      base
3)      stone chain
4)      screechy metal
