Foxes

Very small patch

Map:
-Fixes the air injector in the air tank and the syndistation
-Puts the PDA server room on the main electrical grid (will probably change this back).

Others
-Adds in foxes! Big thanks to Nien and Full of Skittles for the sprites for foxes and Syndifox!
-Can orders foxes from cargo
-Captain has a fox named Renault
-Nuke Ops have Syndifox
-Adds in new critter-crate sprite (old one was pretty terrible)
