Hydroponics

Fixed a horrible bug with the replica pods grabbing non-dead players.
 Wizard
Fixed a potential exploit with the teleport spell (object, of course).
 AIs
Fixed another horrible bug of mine, where the death() proc doesn't process past a certain point.
 Glowshrooms
Now drop to the floor when the walls nearby are destroyed.
 Biomass
WIP added. Do NOT spawn them on live servers unless you want colors everywhere.

Also my code is horrible and I should feel horrible.
