/*QUAKED trigger_keylock (.0 .5 .8) ?
Keylock trigger.  Must target other entities.
This trigger will trigger target entities when all required keys are provided.
-------- KEYS --------
itemkeys: A bit field with key IDs that are needed to open this lock.
sounds: 1 to play misc/secret.wav, 2 to play misc/talk.wav, 3 to play misc/trigger1.wav (3 is default)
target: trigger all entities with this targetname when triggered and all keys have been given to it, then remove this trigger
target2: trigger all entities with this targetname when triggered without giving it all the required keys.
killtarget: remove all entities with this targetname when triggered with all the needed keys.
message: print this message to the player who activated the trigger when all needed keys have been given.
message2: print this message to the player who activated the trigger when not all of the needed keys have been given.
noise: sound to play when lock gets unlocked (default: see sounds)
noise1: sound to play when only some of the needed key were used but not all (default: misc/decreasevalue.wav)
noise2: sound to play when a key is missing (default: misc/talk.wav)
wait: prevent triggering again for this amount of time (default: 5) - applies to target2, target3, target4.
---------NOTES----------
If spawned without any key specified in itemkeys, this trigger will display an error and remove itself.
message2 and noise2 will be resent to the player every 2 seconds while he is in the trigger zone.
