Update Saltern-2.

[Merrokitsune]

About the PR

Saltern-2:

• Added alerts computer to the engineering front room.
• Reinforced arrivals and cryopods.
• Added recycler to salvage room.
• Added instrument spawner in dorms, as well as a wooden table, wooden chair, and several carpets.
• Minor adjustments

Why / Balance

• Saltern-2 is probably the only map (if not one of the few maps) without a functioning alerts computer. This can force engineering to go search for rooms.
• Because of the positioning, arrivals and cryopods still get spaced pretty often. The windows had to be reinforced.
• To accomodate the new salvage update, a recycler has been added to the salvage room.
• Dorms needs some love.
