Notification support in modular computer apps and CIMS (#54724)

Allows modPC programs to send alerts, and adds a proc in the computer object to handle playing the sound effect and sending a message to visible users. These notifications can be muted on a per-program basis. Programs can also set themselves to highlighted in the NTOS Main menu; this is intended to be used along side alerts, but really can be used any time a program wishes to tell the user there is new information.

NT CIMS (SM monitor) now plays an alert during SM delaminations if the app is closed. The app must have had an SM selected before closing, or it will not send alerts. Notifications are sent when the SM makes a radio alert. If the app is currently the active program, the app will instead send a notification just once, when the SM begins delamination, so as to not annoy engineers that are already aware of the issue.
