Needed to support different indicators for advanced mode

Replacement code to speed up work on the map and fighting mistake 'manual control lost' when connected joystick with armed UAV

Added a signal handler to force toggle the switch. Not sure why the normal signal is not being respected.

Moved "Grid Lines" out of General Options and into the Video Stream Widget
Made a QGC custom Switch element

Clarify the title of the "Video Stream" panel (instead of just "Video")

The failure got triggered by 3c55e2b0
