    [Dap] Write metadata to copied files if needed
    
    This patch fixes the bug where podcasts need to be resynced each time banshee
    restarts by writing the metadata out to file for SyncStamps >= Update Stamps.
    
    It should also fix syncing when the "write metadata to files" flag is off.
