WMF: Improved error reporting.

Browse Source 
When loading the source fails because the file format is not supported, we
now report a FormatError instead of a ResourceError.
When the file format is supported but the media cannot be played (topology
cannot be resolved), it is most likely caused by a missing codec and we
then report a FormatError.
