Updated:

Singularity Engine
-Recoded some parts, still works mostly the same
Welders
-Recoded, it works mostly the same but is easier to use in code
-Cyborgs have a larger fuel tank
-Brought most if not all of the areas that use welders upto spec
Moved the changeling chem recharge code into the human life proc
New players who log out before spawning in are now deleted
New minor Common event
Machines around the station use more power, system might need some changes later
