[Emms-patches] darcs patch: Fix bugs in the browser's cover handling

[Tassilo Horn]

Hi all,

 - If emms-browser-covers value is a function, call it with a directory
   as its docs say.  (Before it was called with a file)

 - Also add to its doc-string that its second arg is a symbol (its
   size).

 - Support all image types emacs knows.
