Does not correctly parse REM GENRE/COMMENT if unquoted.

[kevinlekiller]

Hello, I have cue files created by foobar2000 and/or metaflac, the GENRE / COMMENT REMs are unquoted, for example REM GENRE Progressive Rock.

libcue will print to stderr:

bad character 'R'
bad character 'o'
bad character 'c'
bad character 'k'

And cdtext_get(PTI_GENRE, cdtext) returns Progressive.

I fixed this issue by using find / sed on all my cue files to quote the genres / comments, although it would be better if libcue could support these cue files without editing them.
