ogg123 now plays FLAC files!
- Added stuff into configure.in to detect FLAC libraries and headers (should autodetect correctly, but you can also force it off with --without-flac) as well as setup conditional building. - FLAC is not required to build ogg123 (unlike curl). - Reads both FLAC and Ogg FLAC - Refactored vorbis comment pretty printing into separate file since it is shared by both FLAC and Vorbis readers (and future Speex reader will need it too) - Fixed bug caused by assuming Vorbis comments were null terminated. svn path=/trunk/vorbis-tools/; revision=4222
