Alternate messages for stuff while hallucinating + some tweaks

Created by: unid15

-Chance of fake shuttle call and fake delta alert reduced greatly, they should be very rare now -Added is_blind() and is_deaf() procs for mobs -Added spook() atom proc and reworked Boo! to use it -visible_message proc has three more optional arguments - drugged_message, self_drugged_message and blind_drugged_message -Added hallucinating() proc for mobs which determines if they see drugged_message, self_drugged_message and blind_drugged_message instead of their normal versions. If the user took space drugs / mindbreaker recently, it returns 1. It takes more mindbreaker to get the effect -Added simple_message() proc for mobs which works like src<<"message", except that it takes two messages - one is shown normally, other one while hallucinating. Example: M.simple_message("You hit [A]", "You hug [A]")

-The following stuff now provides alternative messages while hallucinating:

-crematorium, gibber, telebatons, stun batons, soap, banana peels, welding tool, soldering iron, health analyzer, medbots and both secbots and more -passive genetic powers have a random message when activated or deactivated, meaning you don't know which one you've got (doesn't affect disabilities, passive powers which give you an overlay i.e. heat resistance, and active powers) -you can't make out reagents correctly in glasses and beakers
