Cryo in medbay should be clickable to change temp

[Nightgunner5]

I'd be lying if I didn't say I've wanted this at some point. But in all honestly, what's the point? I mean, it would literally save you MAYBE 3 seconds of time. And since you only have to set up cryo once, it doesn't add up to that much time even if you decide to play medic for the next 50 rounds. Sure, it could be more efficient, but only a little bit.

Since the cryo chamber only ever gets set to one temperature, why not just have it start there and have some button you need to push to enable cooling instead? If someone were to want to disable cryo healing, they'd have a much easier time putting in a beaker of poison or stealing the oxygen or something.
