- Speex support for ogg123. Reads comments and all that, but does not

  calculate the total play length of the file.  Chained streams don't
  work yet either.  Just like FLAC, this support is optional and can
  be disabled at build time using --without-speex.

- Fixed some very silly printing bugs that prevented metadata from being
printed at the right verbosity level.
