Support TLS/SMTPS

[probonopd]

Can this be extended to support SMTPS (Simple Mail Transfer Protocol Secure) using WiFiClientSecure?

You may have seen in the comment of ESPMailer.cpp, that TLS/SMTPS is planned, but currently not implemented (need to play around some more to do the handshake in the right place).
But if you've an working idea, feel free to push.
