metatags_quick compatibility

Hi everyone
I was trying to use this module with metatags_quick keyword fields.
I got the error:
Notice: Undefined index: metatags_quicks in _keyword_rules_extract_tags() (line 178 of [...]/sites/all/modules/seo_checker/keyword_rules/keyword_rules.module).

I solved it by adding the following lines in the function _keyword_rules_extract_tags() in the switch code block:

case 'metatags_quick':
          $keywords = $form_values[$keyword_field][$form_values['language']][0]['metatags_quick'];
          $tags = drupal_explode_tags(strtolower($keywords));
        break;

I hope this is useful.

PS.: sorry for not publishing a patch....don't actually know how to do it.
