Moves the SMESeses into a purpose built SMES room (the old Grav room)

The new room has some redundant wiring and physical distance from maint halls that should help thwart lazy bombing attempts.

Removes requires_power from the SMES area, I've seen no side effects from doing this.
Rewires the Collector to SMES wiring in yellow to aid in comprehension/safety

Removes the old SMES nook and replaced it with a little tat for the inevitable plasma fires that ravage the room with shocking frequency

Moves PACMAN to the SMES room
