Title: NullTransport should report that all emails have been delivered.

The PHPDoc for ```NullTransport``` says:

> Pretends messages have been sent, but just ignores them.

However it returns ```0``` from ```send()``` method saying that no mail has been delivered.

It should return number of recipients.
