Add metadata editor for audio files

A growing number of users want to edit the metadata of their audio content in the VLC app. Maybe we should add an editor?

changed milestone to %4.0.0

added Feature MediaLibrary user feedback labels

Hi Felix, Can you assign this to me . From what I understand a view needs to presented that show all types meta type of audio and textfields below it and submit button to save the changes.

yes and we need to check if the backend in libvlc is actually there to make the changes persistent. Modifying the media library data base is one thing, but we might also want to modify the mp3 files (etc.) so if you export the media, the changes are still there.

Having a UI would be a good start.
