==============================
SUB_UseTargets
the global "activator" should be set to the entity that initiated the firing.
If self.delay is set, a DelayedUse entity will be created that will actually
do the SUB_UseTargets after that many seconds have passed.
Centerprints any self.message to the activator.
Removes all entities with a targetname that match self.killtarget,
and removes them, so some events can remove other triggers.
Search for (string)targetname in all entities that
match (string)self.target and call their .use function
