Title: A Mail can now have optional custom headers.

As discussed in [issue #104](https://github.com/joscha/play-authenticate/issues/104): a ```Mail``` can now have additional custom headers. Useful for example if you use a mail sending service like Mandrill which uses mail headers to configure the sending process or selecting templates and sending merge variables.
