At that point the vehicle is gone, so need to to clean it up

Takes less real estate and flows better and small displays

Also fixed problem with setup complete signaling after positive
calibration completed

There are many ways of iterating over lists in C++/Qt.
In the specific case of QStrings, it is known [1] that using
foreach with const references avoids the creation of new
QString objects in each iteration, reducing the time consumed
by the loops.

Also added missing FRAME types

This commit introduces the APM Airframe configuration. The interface
is the same as the PX4 one, but the way we deal with the uas is a bit different

Since the APM stack doesn't provide a xml with airframe definitions a
new one was created by hand with only the values that we need, wich will
trigger a download of the parameters file from the mavlink github

Now it correctly handles the FRAME variable and it's faster
regarding the download of the parameters for each type of Frame.

Only show Airframes for ArduCopter, not for ArduRover nor ArduPlane
