Refs #10755:
 * Toggle the 'user' checkbox with tri-state behavior when one of its associated 'attribute' checkboxes is selected, and toggle all of the 'attribute' checkboxes when their 'user' checkboxes is selected. The HTML for the table was modified to be similar to the ticket listing table on the Query page in order to make the jQuery checkbox toggling easier to implement.
 * The submit buttons are disabled when the page loads, and enabled when at least on checkbox is selected.
Refs #10755: Add a "toggle-all" checkbox to the header.
Refs #10755: Remove the ''Undo selection'' button. The ''Select all'' checkbox provides equivalent client-side functionality.
