Map and Animal fixes!

Simple_animal fixes:
- Mice now properly get added to the mob list.
- Simple animals no longer use emotes if they have a client attached.
- Bears no longer run their AI stuff if they have a client attached.

This means that admins can now use the 'Animalize' button to turn players into mice and bears!

Map fixes:
- That window near arrival shuttle is back where it is supposed to be.
- Nuke op shuttle has red floors again.
- Holodeck's beach program once again has a beach.
- The beach once again is a beach.
- Re-added plating in the centcomm control room (where A.L.I.C.E. is.)

Changelog updated.
