FIX Several issues

FIX "set password" menu: only visible in expanded menu (not in action bar)

FIX Updates app version number

FIX Adds userId field in PlaylistItem, such that it can be stored to the local

    unshown local playlists, due to unsaved user_id (and thus failing WHERE
    clause of query).
