*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

Added var denoting which direction is fore of the ship.
Adjusting speed now applies movement effect on ship's zlevel.
Added working engines system. Only defined type currently is thermal engine.
Acceleration is now based on total thrust and ship's mass.
Added engine control console.
Changed shuttle control console to use custom interface to pick destinations.
Shuttles can now go between any types of sectors, not just ship->sector.
Shuttles cannot return to base if they are too far on overmap.
Moved helm computer to NanoUI.
Helm computer now stores navigation data records instead of polling info from actual overmap objects every time.
Metaobjects now can define if sector is well known, in which case it will be automatically added to helm computer records on creation.
Can add and delete records.

-metaboject with zlevel info that should be placed on sector/ship zlevel
-overmap object that represents a map zlevel
-startup hook for building the overmap
Also removes the now unnecessary get_cure_threshold() proc, caps the
rate at which an organ can receive germs from wounds, and makes germs
spread from external to internal organs happen one organ at a time
instead of all at once.
