Bug 11364: Label layout types and text justification types are not translatable

To test:

1) cd misc/translator
2) perl translate update xx-YY
3) check that there's no msgids that contain the layout types or
   text justification types in po/xx-YY-i-staff-t-prog-v-3006000.po
4) apply patch
5) perl translate update xx-YY
6) check po/xx-YY-i-staff-t-prog-v-3006000.po that it contains the
   msgid for the frequencies. (search for "BLOCK translate_label_types"
   and "BLOCK translate_justification_types")
