Partial fix for pAI emotes (one-third-reimplementation of audio emotes)
Cleanbots are now created unlocked.

Allows roboticist to set up cleanbots and if they patrol or not.  Requires janitor access to lock them (Captain, HoP, Janitor)

Should probably have a proc that checks you have either of the access listed but for now this fixes this minor problem.
Fixed placing ID's into PDA's that are on the ground.

Removed useless can_use check, no reason that is needed there.
Mixed up some whitelist flags.
