Add a 'Revert changes' button

(In [12421]) Refs #10690: Added a Revert changes button.

The Revert changes button is enabled only when the list is changed. This got me thinking that this plugin could provide some other similar features:

• Disable Remove selected items on page load, and enable it when a checkbox is selected.
• Disable Apply changes until the list order is changed, or one of the Default radio buttons is selected.

I tried "Revert changes" feature. If reload after using "revert", the browser shows the confirmation.

It would be better to reload without confirmation.
