Medbay Areas Revamp

- Light Switches added in most new rooms, Morgue and CMO
- A vent in the CMO's Office that literally linked nowhere and was as
thus broken was linked. I did pass it under a rwall, but a working vent
is better to me
- New areas shown here (http://i.imgur.com/ADyDGn0.png) : Surgery
- New areas shown here (http://i.imgur.com/PbY7FHM.png) : Patient Room 1
and 2, Medbay Break Room, Ghetto Surgery, Vent change in CMO
- New areas shown here (mostly so) (http://i.imgur.com/Cv4HOw7.png) :
Virology Break Room (everything above the second cycling door minus the
maint part on the left)

As far all new areas (minus Surgery which already existed as is) are
concerned, I had to create new areas instances. It might be good or not,
but it functions when ran

Not part of Medbay Area Revamp but still done :

- Fixed Science further by removing a small outcrop of R&D areas that
caused some lights in the Science hallways near the double door entrance
to go out when the R&D lightswitch was used
