dislayFormat für discsubtitle

[x-stefan]

Thank you for checking this issue. As I wrote, I can't see what's wrong:

Code:

find . -iname "*.flac" -exec metaflac --list --block-type=VORBIS_COMMENT '{}' \; | grep DISC | sort -u
    comment[14]: TOTALDISCS=04
    comment[15]: DISCSUBTITLE=I Psalmi Verspertini
    comment[15]: DISCSUBTITLE=L'Eloquenza Divina
    comment[15]: DISCSUBTITLE=Spiritualità E Liturgia
    comment[15]: DISCSUBTITLE=Vespro Dei Martiri
    comment[3]: DISCNUMBER=01
    comment[3]: DISCNUMBER=02
    comment[3]: DISCNUMBER=03
    comment[3]: DISCNUMBER=04

At least DISKSUBTITLE are working (in bubble) without displayFormat in the config.
