Include total delegates in results

[wmandrews]

It would be great to include the total delegates and total superdelegates as candidate fields that can be added to the elex_results table. This will make it easier to make more advanced results views that include total delegates without making an extra AJAX request to the delegates API endpoint.

Looks like national delegate and superdelegate counts are in the delegates table as national rows, with state equal to US. I can add a field to elex_results that attaches those counts to each results row (or at least state rows).
