Large updates to Rei's Medbay

If I didn't fuck up massively, this contains the following

- Shuffled Genetics and Morgue
- Switched Cloning to now be a lobby of sorts, open to the Hallway
- Medbay/Science Maint opened into a simple hallway to allow Chef access
- Paramedic Cryo Tube has been removed
- A few more miscallenous changes
