HTML Body PostProcessor (integrating PreMailer to 

The best bet to styling html emails is to set the style attribute in the corresponding tags. However, most people usually have their style definitions in separate css files. There is plenty of documentation about this on the web (http://css-tricks.com/using-css-in-html-emails-the-real-story/).

So I have modified mvc.mailer so html body is passed through a list of configured post processors. One of this post-processor (based on the premailer library) removes style definition from the head tag and apply the rules to the corresponding tags in the body.

I followed the preprocessor pattern of SquishIt library. I hope this modification gets integrated to the master branch. 

You've done a great job with Mvc.Mailer. I am using it in several projects. Thanks guys!
