Enable TrackIR in more cameras

[weezzah]

Suggestion 1: TrackIR is only enabled for the in-cabin camera as of now, but it would be great to have TrackIR enabled in more cameras, preferably enabled in all of them:

• In-Cabin camera (TrackIR enabled)
• Orbiting Camera
• First-person camera / Walking
• In-vehicle cameras

Suggestion 2: A really practical feature is to be able to rotate the camera while in a TrackIR enabled camera. Essentially changing the view direction. This is useful for cabin and vehicle cameras, and later on for shunting operations driving both directions, etc.
