Title: Gimbal status reporting

This changes the way the gimbal reports it's orientation to the GCS. This is useful for plotting the footprints since the orientation of the gimbal is required. ([example](https://www.youtube.com/watch?v=aZP1bBvMXSI))

The status is now reported periodically (instead of on request), and it's always the attitude of the gimbal.
