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

Adding missing qgcView to QGCMapPolygonVisuals instance in SurveyMapVisual.qml

Android done.

all calls to qsTr are done, if I didn't forget anything,
on the PX4 QML files.

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.

The parameters for calibration were changed in the latest master. QGC
needs to work with both. Hacked in for now, waiting on a true parameter
re-mapping implementation.
