* Make the crew monitors beep when someone dies or crits

* Cleanup

* Fix a comment that was not updated earlier.

Signed-off-by: Quanteey <61941975+Quanteey@users.noreply.github.com>

* Switch frame time tracking to using timespans

* use timestamps of next alert instead of frame time tracking

* Fix outdated docs
