DevAdapter print_email option should highlight links

[jwoertink]

It would be cool if all of the URLs in your email were like green or something when you use the dev adapter to print emails. A well designed email is LOADED with markup, and printing them to find your "confirm email" link is pretty difficult. Since the rest of the text comes out in the basic color, if we had a way to colorize the URLs, then it'd be easier to scan your terminal to find it.

To do this though, I get we'd have to re-parse the HTML which means we'd have to include an HTML parser, and things get messy. So this is more of a wishful thinking, but I'm posting anyway just in case someone gets an idea of how we can do this without it getting too crazy and requiring 3rd party shards.
