MAVLink dialects can now be specified as a list, so multiple dialects can be compiled in simultaneously (may result in conflicts between dialects).
MAVLink dialects are checked for existance before support is added.
Users are notified of which dialects are used and which cannot be added and why.
The README now has info about specifying MAVLink dialects.

The default UAS.cc now lists available actions that it can be commanded. These are polled by the Joystick Configuration window for each joystick button so that they can be assigned to trigger this action. Button presses don't yet trigger these actions, nor are they stored and reloaded on UAS switch.
