Adds a crew monitor program to modular computers (#12705)

* Should add crew monitor program

Fairly basic, just exports the crew monitor UI and imports it in a different Ntos UI like how secureye was done.

* Forgot this

ctrl C ctrl V failed me again

* Adds an alarm icon and adds theos's request

Took me long enough to do this

* Forgot about the define

this is probably important

* Changed the header icon and made it update with alarms

Forgot to change this when mashing ctrl C ctrl V

* Fixed alarms and ported header icons from bay

Fixed alarms triggering from off Z level deaths and ported header icons from bay. Untested, but parts of this already existed on my test server so it should work.
