Allows QGC to run on Raspberry Pi 2 with direct framebuffer (X/startx
not needed). Memory split seems to need 128 for GPU. Qt5 needs to be
configured with "-opengl es2 -qpa eglfs -device linux-rasp-pi2-g++".

Selected flight mode is controller by firmware. Use selecting flight
mode cannot set the check, or it will be wrong if firmware declines
change.

Users are getting confused because we are missing images. Will put back
new fancy version once we get new airframe config plus auto-generate of
images sorted out.
