Numbering on motor command is wrong (or strange), so wrong motors spin
when using sliders

virtual marks a method for inclusion on a v-table, but we don't want
the methods of classes that won't be inheritable to have a v-table,
we want, however, to issue a warning if somebody try to inherit
that specific class and reimplement those methods.

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

Refactored PX4 radio config to work with both PX4 and APM

HIL config improvements, fixed confusion about which dock widget is part of which view, main window behaving now

Pushed HIL with X-plane to being close to operational. Receiving from X-Plane  implemented, sending to it is prepared. Needs an iteration of onboard SW first
