The size of the to-be-created thumbnails was passed from DivePictureModel to Thumbnailer. This became more and more bothersome, because the size had to be stored with the request. Calling from Thumbnailer into DivePictureModel was not an option, since this is not linked to all tests. Therefore, move these functions to the Thumbnailer class. Since the maximum thumbnail size is now known to the thumbnailer, the dummy and failure images can be precalculated, which makes switching between dives faster.
