There is no such things as a clicked signal on QWidget. You activate
new UAS from right-click menu.

The connect call was generating debug output to identify that it was
failing. After looking at the code realized that this connect is not
needed. The group box is removed when UASListWidget::removeUAS method
is called.

Second change in the file fixes a crashing bug when the last UAS is
removed. Need to exit the iterator after we modify it.

Altitude splitted to altitudeAMSL and altitudeRelative, speed splitted to airSpeed and groundSpeed. PrimaryFlightDisplay uses airSpeed for FW and groundSpeed for MC.

Replace 9 seperate valueChanged() signals with just 1, and remove the resultant tons of code duplication

Checkpoint: RC calibration much better / operation, can use UI tweaks. Airframe config in, but not operational and still very functional / ugly.

Change so UASQuickView font sizes are now identical, and change properly based on window size and column count

Anton and I noticed that the message view stops autoscrolling properly
sometimes when there's a high frequency of arriving messages. This
should fix that problem.

Have settings loaded/stored correctly for all joysticks based on their UAS type and autopilot type. Switching between UASes doesn't work right yet, however.

Some comment cleanup, and fix so when closing the main window, it also closes the item select window

The QGCUnconnectedInfoWidget now remains square and has more rounded edges so that it looks more like a button.

Finished merging QGCVehicleConfig.ui, which I hadn't done properly last night. Things are now in a usable state again.

The details on the success/errors for the MAVLink protocols are now shown for each link as tooltips that are updated every 5s. Values are currently wrong and unsure why as of yet.
