Cleanup from coder module suggestions

I ran this module through coder review and it had a few really minor suggestions. I've cleaned them up and now coder passes 100%.

Here is the list of items it wanted fixed (all spacing related):

1. Line 328: Use "elseif" in place of "else if"

else if ($error['error_element']['url']) {

2. Line 707: String concatenation should be formatted with a space separating the operators (dot .) and the surrounding terms

$output .= '

'. drupal_render($element['url']) . '

';

3. Line 1208: String concatenation should be formatted with a space separating the operators (dot .) and the surrounding terms

$email_pattern = '/^mailto:' . $user . '@'.'(?:' . $domain . '|' . $ipv4 . '|' . $ipv6 . '|localhost)' . $query . '?$/';
