Map modifications

- Added a Microwave in the Ghetto Bar
- Added lightswitches in Botany, Pod Bay, Execution Chamber, Courtroom
and Ghetto Bar

Mostly done for ghost fuckery and since those rooms have a fair amount
of lights and yet no lightswitches. The microwave in Ghetto Bar was also
requested by a player
