External Libraries: Upgrade PHPMailer to version 6.6.5. 

This is a maintenance release with minor changes:
* Don't try to issue `RSET` if there has been a connection error.
* Reject attempts to add folders as attachments.
* Don't suppress earlier error messages on `close()`.
* Handle `Host === null` better.
