- MultiVehicleManager is a Qml friendly replacement for UASManager
- Vehicle is a replacement for both UAS and AutoPilotPlugin

Also:
- Prompts to reset trims to zero prior to calibrate
- Turned of radio check for now since it prevents spectrum bind

QGCUASParamManager and friends are replaced by FactSystem

Also converted to new logging category

Subclass of QMessageBox which re-implements the static public
functions. There are two reasons for this:
1) The QMessageBox implementation on OSX does now show the title
string. This leads to message boxes which don't make much sense. So on
OSX we set title to text and text to informative text.
2) If parent is NULL, we set parent to MainWindow::instance. This
prevents message boxes which can go behind MainWindow

This allows you to determine if full parameter list is ready if you
missed the parameterListUpToDate signal.
