ext/ffmpeg/gstffmpegcodecmap.c: Generalized palette functions, add actual mimetypes for wing commander formats.
Original commit message from CVS: * ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_codecid_to_caps), (gst_ffmpeg_caps_with_codecid), (gst_ffmpeg_caps_to_codecid): Generalized palette functions, add actual mimetypes for wing commander formats. * ext/ffmpeg/gstffmpegcolorspace.c: (gst_ffmpegcsp_chain): Ffmpeg has internal palette functions, so I noticed. * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_chain): Actually remove all palette code.
