Cryo in medbay should be clickable to change temp

[Winged_Chiller]

Since the cryo chamber only ever gets set to one temperature, why not just have it start there

And while we're at it set the all the SMES to the proper outputs and inputs, and have toxin gas pre-mixed, have the engine start itself and replace all the players with the AI versions.

Removing these small nuisances just makes the game too streamlined. I like it to have a small sense of tedious realism, it helps immersion, even for goonstation.
