dlgtrackinfo - editing covers - associates a popup menu to the cover art
implements removeCover action - it disassociates a cover of a track
- after that, future requestPixmaps will do the "searching step".
Should we handle it and avoid doing searchs after a purge?
Editing covers - using the current cover dir as the initial filedialog dir
dlgtrackinfo - removing txtfilepath
CoverArtCache - Rename method - using extractEmbeddedCover() instead of searchEmbeddedCover()
Reloading cover from metadata + question box
Handling cases when:
- embedded cover is different from de current cover (ask if want to change)
- current cover is not NULL but embedded cover is NULL (ask if want to remove)
Add the action "Reload from Metadata" to the popup menu
