Title: Enable downscaling cover arts for 'fetchart' and 'embedart' plugins

Add 'maxwidth' option to embedart and fetchart plugins.

artresizer.py instances an ArtResizer object that uses internally the PIL; ImageMagick or a web proxy service to perform the resizing operations.
Because embedart works on input images located on filesystem it requires PIL or ImageMagick, whereas fetchart is able to do the job with the fallback webproxy resizer.
