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.
