SC Stupid Sized Map Update

Or how Woodrat spent too long on something that was supposed to be simple.

- Addition of a Explorer Radio Channel and headsets.
- Explorers and Search and Rescue job slots added
- Adjustments to the pilot job including getting rid of the flatcap
- Map fixes, adjustments, (including signs pointing to cryo) planetside side map additions splitting up of the wilderness into two area sections
- Disabled lighting on the arrivals shuttle area once it is docked with the station, should help with the whole issue of lighting bugging out and having dark space
- Fixed EMS jacket missing icons
- Fixed Research signs being missing for some reason, addition of directional signs for cryo
- Addition of a Search and Rescue Winter coat
- Probably a dozen other small bug fixes I forgot, and bug additions

Tested, seems fine. At least in short tests.
