Two minor UI tweaks.

1) Change the default color updatedOnly color to something that ressembles how cornflower blue looks like in my mind.
2) Change the manualcontrol setting UAVO so that none appears first, which has the effect of starting the comboboxes at the top of the list, instead of the bottom.

#2 is actually a change that requires redoing the transmitter setup. We don't have many users right now before the officiali release, so it's hopefully not too much of a burden.
