Adds support to better handle air alarms in sensitive areas and vents with custom settings

Air alarms now have a new setting, breach_detection, which allows for disabling the automatic mode change when a breach occurs.

Vents now have three new settings. These are primarily for when air alarms request a mode change to ensure that custom pressure levels/checks (in terms of mapping, not set later in game)  are not lost.
