Take non-audio files to the new directory when renaming albums
I think subject says it all. When bliss is auto-renaming files and album directories according to tags and if the album name is different than the directory where the current album is stored, it creates a new directory in correspondance to the album name and moves all files there in, however non audio files (like pdf, additional art directories) are left behind in the original directory. The make this fantastic feature really useful, the whole content of the old directory should be moved to the new one.
It has always been intentional not to move other files (note we should also move image files though). That's partly because I'm not sure what to do about name clashes.
