More map buggery

*Fixed the mulebot beacon in kitchen to accurately reflect location
*Fixed that bug in the supply shuttle with the missing wall corner
+Gave Ruskie a space cleaner bottle
-Fixed an erroneous disposal pipe outside medbay.
*Implemented more experiments with disposal pipe; currently, QM, Hydro,
and janitor disposals are running on this system. I doubt it works
currently, but we will see.
+Added a disposal room. Currently, only people with cargo access can get
there.
+Added some more goodies in space. Space divers might find some
useful/contraband stuff, assuming the Ruskie doesn't get it first.
+added a gun turret to mining station. In theory is there to fend off
spess carp. In practice probably won't kill them all before getting
trashed, due to the carps' ferocity now.
+added a reset module to the AI upload chamber. Seriously, why did that
get taken out?
+added a phazon somewhere moderately difficult to reach
*Attempted to fix spawn points of the shaft miner and cargo technician.
Needs testing to see if worked.
+put a spess carp back in terralabs
-removed the spess carp spawn points from centcom. This was bollocks.
*Fixed firelock faggotry. How did this get unfixed?
