Currently mails sent from jenkins look pretty ugly.

They are text/plain, which is ok for most cases.

BUT especially when you have plugins, which use colors in the output the mails are not human readable, as the important information which is transported twice (once in colors, once in words) is not instantly recognizeable by humans.

So please allow to send the mail as text/plain + text/html and pass the complete styled html from the console view to the mail.

This way behat testers and other frameworks users, which heavily rely on colors have instant easy to read feedback via mail.
