- 80% of the "Rename & Move files based on tag information" thing. Lacks

  a configuration dialog. Currently the KAction in juk.cpp is commented out
  so that the merkin doesn't get anal about stuff which does not work yet.
  Also, there's a return in FileRenamer::moveFile() because I don't trust it
  yet.
