Added NTLM authentication

I added ntlm auth and tests. Not sure if the configuration files are right.

I cleaned my fork up and created a new pull request cause this was easier for me than cleanup the other repo. So it's the same as https://github.com/swiftmailer/swiftmailer/pull/388

Merge signed message
feature #286 Merge signed message (xdecock)

This PR was squashed before being merged into the 5.1-dev branch (closes #286).

Discussion
----------

Merge signed message

Merge SignedMessage class with Message as it will simplify documentation.

Keeps Swift_SignedMessage as deprecated for a few releases as it's a "free" file, but it does not have any reason to be splitted
