All those @since X.X.X are just trash to the eye, since you learn to ignore that why not clean it up?

They make sense if you are building an API for a library, but since everyone can see the whole code and even get better descriptions via [git blame](https://github.com/ne0fhyk/droidplanner/blame/d2e50979219341ecef76ef7d2bca4801747b1d20/DroidPlanner/src/com/droidplanner/MAVLink/MavLinkHeartbeat.java) those tags are useless.
