move quick dialogs example into an artificial subdirectory again

The trouble with Id28d5718b4b7b475dcd7d62e31c4634219dc3ddc is that
the build assumes that all example directories are subdirectories, so
the examples-manifest.xml will point to the wrong place and creator
ends up not having the example on the welcome page.  That's more rigid
than it should be, but we might as well use the opportunity to
distinguish system dialogs from any QML-only dialogs that might be
added to this module later on.

stabilize tst_touchmouse.

The test relies on window activation, which means that it
cannot be a parallel test.

photosurface demo: behavior depends on initialization order

The file dialog wasn't appearing on the mac.  This way seems to work.
We have a long-term bug here but this workaround will look better for
the release.

QColorDialogHelper: Force QWindow before setting flags

This needs the same fix as the one in the QFileDialogHelper (change
I7a3b2321f4a1bf179dced8e98598559f396386db).  However to be even safer,
we can check for a null pointer before calling any methods on the
QWindow.
