Change version number of oggenc to 1.0.2.
Remove hardcoded reference to libvorbis version, as this is usually wrong. Need a libvorbis call to get a version string (such as the vendor string). Update documentation in --help message to: - fix badly wrong documentation of -b - document the --managed option - document the -v option - clean up documentation of a few other related options. svn path=/trunk/vorbis-tools/; revision=9021
