Option not selected in Walker_CategoryDropdown

[tlexcellent]

In function start_el() of class Walker_CategoryDropdown (wp-includes/category-template.php), when argument value_field is set, selected option should check value_field and not always term_id.

Change :

if ( $category->term_id == $args['selected'] )
  $output .= ' selected="selected"';

For :

if ( $category->{$args['value_field']} == $args['selected'] )
  $output .= ' selected="selected"';

In category dropdown, 'selected' should match against 'value_field'.

Props tlexcellent.
