All metadata is now extracted from Vorbis streams and ICY streams and exported as new <metadata> tag into admin/stats if specific mountpoint is requested. To testers: - Please test with Ogg Vorbis streams. - Please test with Ogg Vorbis + Theora streams. - Please test chained Ogg streams. - Please test with ICY streams. close #2106
