QmlDesigner: Cache last image in 3D view and add busy indicator

Browse Source 
This patch caches the last image from a document/model.
The result ist that when reopening a file in the 3D editor
the user sees immediately something.
Since the view is not interactive, yet, we show a busy indicator
until the view is fully initialized.
