Reversal of Views check_plain() call should include ENT_QUOTES

Basically single quotes are encoded by check_plain() and result in ' because check_plain specifically encodes with ENT_QUOTES set:

<?
function check_plain($text) {
return drupal_validate_utf8($text) ? htmlspecialchars($text, ENT_QUOTES) : '';
}
?>

However as part of nodereference_allowed_values(), the values returned by Views are decoded without ENT_QUOTES:

<?
// Views theming runs check_plain (htmlentities) on the values.
// We reverse that with html_entity_decode.
$options[$key] = html_entity_decode(strip_tags($value['rendered']));
?>

So single quotes still remain encoded. (And will show up as encoded values in select lists)

Patch included.
