Made Q3D emit updateWidget so that local view updates correctly.

Tweaking the documentation for QFileDialog and replacing the doxygen "@" escape to be consistent with the rest of the code.

QGCApplication::saveTempFlightDataLogOnMainThread()
MainWindow::startVideoCapture()
QGCBaseParamWidget::saveParametersToFile()
QGCDataPlot2D::savePlot()
QGCDataPlot2D::saveCsvLog()
WaypointList::saveWaypoints()
QGCToolWidget::exportWidget()
LinechartWidget::startLogging()

Making sure defaultSuffix doesn’t start with a dot (i.e. “.bar”)

QGCFileDialog::getSaveFileName()

Assert if defaultSuffix contains a dot (i.e. “.bar”)

UnitTest::_getSaveFileName()

Added appropriate AcceptMode to AcceptSave so the OpenFileSave shows the proper Save button instead of the default Open button.

Revert premature assumption that adding support for selected filters in Open Save would not affect all other file dialog operations. As is, unit tests requires all or nothing.

WIP issue #1173. Adding default suffix (extension). While at it, added selected filter support and removed unit test assert about its use.

Rc param tune

Vim YouCompleteMe config

Rework Connect toolbar button usage

Don't use native widget siblings

Adding Issue #1157 to put back

QQuickWidget can’t handle this

Now works for more than Serial links

Move ui style from MainWindow to QGCApplication

Moving more things off of MainWindow

Moving methods from MainWindow to QGCApplication so that more things
can run without a window. Helpful for testing.
