Γιώργος Κυλάφας submitted this patch for the JuK file renamer to use the proper
"directory mode" of KFileDialog for the music folder selection in the File
Renamer configuration.

It's *much* appreciated -- this represents the first non-Michael Pyne
contribution to JuK since about 8 months ago (and the one before that was 20
months ago).

I will backport to 4.6.3.
