START_OPEN	the door to moves to its destination when spawned, and operate in reverse.  It is used to temporarily or permanently close off an area when triggered (not useful for touch or takedamage doors).
NOMONSTER	monsters will not trigger this door
LOCKED - door won't open until used by a non-player entity

DUAL_TARGET - door fires target on both open AND closed, instead of just open

"message"	is printed when the door is touched if it is a trigger door and it hasn't been fired yet
"sp_message" is for a string package ID (numerical)
"angle"		determines the opening direction
"targetname" if set, no touch field will be spawned and a remote button or trigger field activates the door.

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

START_OPEN	the door to moves to its destination when spawned, and operate in reverse.  It is used to temporarily or permanently close off an area when triggered (not useful for touch or takedamage doors).
NOMONSTER	monsters will not trigger this door
LOCKED - door won't open until used by a non-player entity
USE_TARGET - door can be used by player even if it has a targetname
IGNORE_HACK	- use this flag if the door's origin is not at the edge (hope you're happy, Zuk)

You need to have an origin brush as part of this entity.  The center of that brush will be
the point around which it is rotated. It will rotate around the Z axis by default.  You can
check either the X_AXIS or Y_AXIS box to change that.

"distance" is how many degrees the door will be rotated.
"speed" determines how fast the door moves; default value is 100.

REVERSE will cause the door to rotate in the opposite direction.

"message"	is printed when the door is touched if it is a trigger door and it hasn't been fired yet
"sp_message" is for a string package ID (numerical)
"angle"		determines the opening direction
"targetname" if set, no touch field will be spawned and a remote button or trigger field activates the door.
