Updated the additional MetaStation map from v22A to v22E, added in-game Map sprite

Ok, this is my first attempt at a pull request, please tell me if something is wrong here. The only changes should be deleting the old MetaStation 22A and replacing it with MetaStation 22D

Updated the additional MetaStation map to v22E from 22A:
v22E
-Added wall-mounted map posters around the station, adding sprites for these to decals.dmi. 
-Improved various aspects of a lot of areas
-Changed area designation of space outside the vault
v22D
- Added a few small changes to maintenance and some other areas, adding a few MULEBOT delivery points that were missing, as well as one to disposals.
- Fixed the APC direction in the janitor's closet
v22C
- Made some changes to the shuttle to make it nicer
- Fixed some problems with the atmos burn chamber being a bit clunky. It's more usable now.
v22B
- Got rid of table between sleepers in the emergency shuttle. Sleepers should be fine now.
- Remade the AI upload foyer so servers are not doubled unnecessarily.
