Accept nooped plurals in wp_generate_tag_cloud() / wp_tag_cloud().

Renders topic_count_text_callback more or less obsolete. It can still be used, but passing a plural is easier.

Update PHPMailer to 5.2.7 from 5.2.4.

Includes two trivial modifications for WordPress:
 * Doesn't use the autoloader, so the check to enforce the autoloader from the constructor is removed.
 * Requires class-smtp.php for backwards compatibility with direct (non-wp_mail()) uses of PHPMailer, as the autoloader isn't used.
