Rollback is a 1-click tool which will allow a user to undo the edits of the last user on a page, basically nuking all changes back to the previous Contributor. Bureaucrats and Admins already have this ability, giving it to one of them is only for the additional tags in their masthead.
 * 1) Rollback does not allow for making Summaries, so if there is a summary which needs to be made, rollback is not the tool to use.
 * 2) Rollback will not discriminate between *when* the last user made their edits, so if only a few "layers" or "steps" of someone's edits need to be reversed, rollback is not the tool to use.
