Fixes mail system

After a long session of staring at pipes, right-click-> delete-ing, and
editing variables, I finally managed to fix the mail system. I added
disposals to every place on the map where there should be one and fixed
the sorters for all the other ones. I had to gut large parts of the
disposals near medbay, but I did it.
Changes not at all related to the mail

- Added more boxes of replacement bulbs around the station, as
requested.
- Added windows between the med/sci RIG storage as to keep someone from
looting both.
- Moved CMO's locker to where one of the disposal units used to be.
Last set of changes. Also nothing to do with mail

- Removed roburger. It seems like a bad idea in retrospect.
- Added sci satchels to xenobiology.
Merge pull request #91 from JacobLee1/master
