[2/3] Extras: Add modified Jack's Music Widget app
Modified the black background option in the widget setting to be
completely transparent. Since this app is modified, any updates to the app
will not be shown in the Play Store updates section. Any attempts to update
will result in failure. Uninstall this app if you wish to update in favor of
losing the modified transparency.
