Dance Bar Update

The Dance Bar has been removed and the hallway leading to it has been re-made into a maintenance shaft. Minor changes to the Library were made to accommodate this. The area the dance bar used to be in has been replaced with an abandoned and powerless bar.

Note that the door looks like an iron door in the picture, but it actually a wooden door.
