 It is possible to click the "Add New Category" button multiple times when
 creating a new category from the new post screen.

 In certain cases, the extra clicks can cause (mostly harmless) fatal
 errors because of a race condition in
 {{{_wp_ajax_add_hierarchical_term()}}}.

 Attached disables the button via JS after the first click and re-enables
 it after the AJAX request completes (successfully or not).
