removed unnecessary list element operations when updating waypoint list view. There is still some crazy updating going on - most probably in the wp widgets

Made param interface more chatty with a status label. No retransmission active yet, but no silent drops any more

Refactoring WP interface, somewhat brittle and untested at this point - use the master branch if you need stable code right now

Made MAVLink parser aware of line breaks in comments, added new servo output packet to QGC and simulation, enabled servo output display in new Actuator View (previous Payload view)
