Updated spawn room to be in line with other maps now that the loadouts have been changed.

(from the discord server)
Mechanic's autoshotgun is now loaded with rubber shells, and got a buff to masterwork quality because the rubber shells were really just that BAD
Assistant's rifle is now a masterwork too, allowing them to kill husks in two headshots and overall making them more useful
You can now change the music at the spawn's room jukebox

Added gaps to the map.
