Added a spinning visual effect to rolling on the floor to extinguish yourself in case of a fire.
Lube will now make you spin while you're slipping.
Water will make you slip on the spot and won't move you forward.
Fixed the bug of wrong mob directions when buckling them while they are lying down.

-Added condimaster to hydroponics as per request
-Removed excess wires in hydroponics left over from when there was an APC inside
-Repiped theatre disposals to not travel under walls
-Moved extra security locker spawns into the equipment room. It's going to be a bit cramped, but the minor inconvenience is offset by the added security bonus.
-Re-added the hilariously unsafe vending machines to science that were moved to the break room, but were never moved back when the break room was removed
-Reinforced windoors no longer start with security access by default (Fixes armory and HoP windoors)

-Added an airlock to the gulag dock
Changes the layer for items on trays to -1.  This makes them display on top of the tray, but not above other things.
Oh, not in cruelty, not in wrath
  The Reaper came that day;
An angel visited this damned sat,
  And took the parapen away.

Replaces parapen with sleepypen that contains 30u of sleeptoxin and 30u of a new mutetoxin that makes you unable to speak.

Mutetoxin can be made with 2 parts uranium + 1 part water + 1 part carbon.
Renamed Abandoned Teleporter to resolve confusion with the actual AI satellite teleporter
Refined the implementation of the AStar algorithm :

*Reorganised and commented used procs for better visibility/maintenance
*Redid the PriorityQueue class
*Changed the euclidian distance to the byond one (so that we don't calculate float and square root when it's not necessary)
*Made the AStar algorithm use the closed list instead of just filling it
*Some optimization in the open list sorting : last entered is first in case of f ties, slightly less tiles are checked now
*Changes the order directions are checked when adding adjacents turfs to make for more 'realistic' path (read less 'drunk pathing' with lots of diagonals)
*Fixed some turfs densities not being check for diagonal movement
*Closed firedoors are now correctly seens as blocked by the algorithm
*Cleanbots now only moves in cardinal directions, like other bots.
*Updated the info text at the beginning of the file a bit
*Absolutely unrelated : simplified the turf.Bless() proc
