Fix deprecated metaflac options

Fixes and improvements from Debian

minor man pages corrections (Debian #669675) + cuetag.1

There's an off-by-one error in cd.c which causes cueprint to wrongly reject
 cuesheets with 99 tracks.  Its actual limit is 98 tracks, and yet as the
 source code notes, the Red Book audio standard permits 99 tracks per disc
 (and 99 indices per track).
 .
 When I looked into this, I saw that:
 .
 1) not only will the same error occur with index numbers, but
 2) the wrong preprocessor symbol is being expanded when checking the index number

It allows to call `cuetag` like so:

    cuetag Björk-Volta.cue *.ogg ARTIST ALBUM TITLE YEAR=2007 GENRE=electronic TRACKNUMBER

 which accomplishes two things:

  1. it pre-selects the fields and specifies their order;

  2. it hardcodes two fields to specific values for all tracks.

 Since the field list is hardcoded for MP3, any fields specified on
 the command line are effectively ignored. This could probably be
 implemented better, but I do not care about MP3 at all.

Ensures that tracknumbers are zero-padded to two digits.
That seems to be common usage.

This avoids truncating long titles/albums/etc.

 * Look for `mid3v2` first and fallback to `id3v2` according to their availability.
 * Added error message if neither of them found.

Thanks, Felipe Sateler <fsateler@debian.org>

Added error: tag to error message.
Corrected output file format error message.
