Title: flightgear: prevent aircraft from flying with no input

This disables using the home altitude for flightgear and also sets the default speed to 0.
A home altitude not exactly at ground level results in a non-zero default throttle in flightgear which makes the aircraft float around.

Furthermore, a debug function to print the output of the flightgear process (which is launched from qgroundcontrol) is added.
