Server crashing and exploit fixes

Added a cooldown to the containment field shocking players
- If a containment field was set up in a small room, it was possible to crash the server by jumping into the field with no way to escape it. This was likely due to the hundreds of spark effects being generated every second, on top of all the other calls it had to make.

Used the existing parent proc to check for proximity, canmove and death on:
- Atmos pumps
- Atmos mixers
- Canisters. (This should finish off issue 397.)
- Crew monitering computer (This one probably didn't need it but it shouldn't change the way it works.)

Added admin checks to:
- datum/mind
- tensioner
If either of these fail an admin check an admin log will be entered into the server logs and a message will be displayed to admins.
