"angle" determines the opening direction
"target" all entities with a matching targetname will be used
"speed" override the default 40 speed
"wait" override the default 1 second wait (-1 = never return)
"lip" override the default 4 pixel lip remaining at end of move
"health" if set, the button must be killed instead of touched
