Support for groups names with spaces

Only when digging through the code I found:

foreach ($roles as $role_id => $role) {
      $default = '';
      if (isset($role_mappings[$role_id]) && is_array($role_mappings[$role_id])) {
        // Surround any mappings with spaces with double quotes.
        foreach ($role_mappings[$role_id] as $key => $mapping) {
          if (strpos($mapping, ' ') !== FALSE) {
            $role_mappings[$role_id][$key] = '"' . $mapping . '"';
          }
        }
        $default = implode(' ', $role_mappings[$role_id]);
      }

So this is supported but just lacks documentation

Added a hint to the role mapping help.
Am not sure how happy I am with the formatting / wording.
Happy for suggestions :)

Thanks for the contribution! I adjusted the language a bit to help clarify the functionality.
