QmlDesigner: Add tooltips to UrlChooser

* Add tooltips with thumbnails to UrlChooser enable preview of image
  formats and meshes
* Add property editor image provider which makes use of the image cache
* Add mesh image cache collector in order to create thumbnails for
  meshes and built-in primitves
* Fix typo in explicit image cache image provider
* Add return value in time stamp provider if provided file does not
  exist
