Convert theme_taxonomy_overview_terms to twig.

no no no.

Having a template that prints a single variable is going to drive our entire front-end community nuts. We need to actually give them something in this template file to override, or at least a hint of where to go to get at what they wanted.

I'm thinking our twig template should look something like this to start:

{#
/**
 * @file
 * Default theme implementation to display a terms overview form as a sortable list of terms.
 *
 * Available variables:
 * - header: The table headers.
 * - rows: The table rows.
 * - attributes: HTML attributes to apply to the table tag.
 * - children: The rendered form element children for this page.
 * - pager: The rendered pager for the page.
 *
 * @see template_preprocess
 * @see template_preprocess_taxonomy_overview_terms
 *
 * @ingroup themeable
 */
 @todo: update this file once http://drupal.org/node/1777532 is resolved.
#}
{% include "core/themes/stark/templates/theme.inc/table.html.twig" %}
{{ children }}
{{ pager }}

Progress on this template might be blocked by #1778968: Convert theme_table to Twig

I'm not entirely sure this is still valid. Some bits seem to be in the sandbox already, some don't seem present at all. Patch fails in both sections.

Setting back to 'needs work' but it may simply no longer be valid.

@artofeclipse can you comment?

@artofeclipse it's in the sandbox, but now needs to be converted/rerolled against core. I can put this on my list to do!
