Minor tweaking of avionics to match some changes I made to huVVer-AVI six-pack. Added an option to make one of the huVVer-AVI MFDs into a PMag controller. This involved wiring in a 4-pin Microfit 3.0 connecter to the two RS-232 ports on the huVVer that can plug into either the PMag serial control signals, or the standard instrument streaming data from the SkyView and OnSpeed systems.

Also added a 20K ohm resistor in series with pitot heat sense line, as recommended by Dynon (actually recommended 10K, but 20K works).
