Quick map bugger

Minor map changes; would have done more but server admin issues got in
my way.

*fixed a missing cable in one of the maintenance halls
*doubled the amount of prox sensors and flashed in robotics
+added a metal sheets item to robotics
*Stretched te Ruskie station by three tiles
+added a bunch of stuff to Ruskie Station to make it indefinitely
sustainable
+added an antique laser for defensive purposes, note that I want to
replace this with a shiper or something later.
