Hospital gown wrong arms

The hospital gown since implementation has had the wrong arm model, it doesn't give a good impression of the server for people who are put in hospital and have to use it as your arms clip through it. It should be a fairly simple fix to assign the right arms that don't clip.

@1000PhoenixI've had a look through most of the arms and the only ones that I could find which don't clip have the player's back invisible.

Just to add to this as its essentially the same thing, females have no back while wearing the hospital gown, unsure if its intentional due to what else shows if we have a full body. 

Added as #329 to the board.
