v2.8.1

Correct encryption types SSL/TLS and STARTTLS

Previously EncryptionTLS correspond to STARTTLS and EncryptionSSL correspond to SSL/TLS.

To avoid confusion in names, two new const were created:

• EncryptionSTARTTLS for STARTTLS
• EncryptionSSLTLS for SSL/TLS

EncryptionTLS and EncryptionSSL are deprecated and will be removed in future.

SendTimeout improved

iota corrections and SendTimeout improved

• new private function sendMailProcess for send the mail. Function is called in private function send
• improved SendTimeout, if 0 then send call directly to sendMailProcess, else, sendMailProcess is called in goroutine and return the result in channel smtpSendChannel if timeout never happens
• change direction of iota for encryption, encoding, and contentType (this don't break anything)
