Get rid of QGCView, QGCViewPanel and FactPanel. All messages and dialogs are now handled in the root window.

They may show up after parameters ready is signaled. No way around this
since this is a protocol problem. So can’t test secondary component.

Passing parameters QVariantMap across C++ boundary was causing crashes
in Qt due to Qml array bugs. Referencing same Fact* across Qml boundary
in multiple QQuickWidgets caused jScript GC to crash.

- properties now hand off of main “autopilot” object in qml
- Added support for summary items through qml

This way you don’t need to know parameter set ahead of time.
