Initial import of Matthias's draft patch for adding video and audio previewing (similar to the file dialog) to Dolphin's metadata panel. Since Phonon is currently in-process only with the memory/ stability issues that come with this, this might have to be disabled by default - we'll see how it goes. Thanks, Matthias!
