Taxistation WIP - Not Ready for Playtesting

Created the map "Taxistation". This map is somewhat playable.
There are stil a lot of things that need to be fixed.
I figured I should make a pull request now so that others can look at the map and possibly find errors where I have missed them.

Currently not ready:
Xenoarchaeology and/or the second mining asteroid has not been touched (currently the same as Efficiency Station)
Derelict z-level not completed
Centcomm has not been touched (currently the same as Efficiency Station)

Current known issues:
The bolt buttons at the security checkpoint do not work.
Cameras could be considered sparse.
Taxis do not enter hyperspace at all, despite them having a hyperspace timer.
There is no CO2 miner (not sure where to put it if at all).
Some of the disposal belts aren't moving in the correct direction.
There has not been enough per-job testing done on the map.
