You Got Your HTML In My Email Client

This is something we've wanted to do for a long time, and it's very nearly here. @Dan Cederholm has been hard at work designing some clean, informative HTML templates and I've been building out the back-end.

I'd be remiss if I didn't mention the tremendous help that @Litmus has provided, showing us how our HTML looks in dozens of email clients to make sure that everyone can see what we're saying. If you send HTML email, you should check it out.

We're starting off slowly with just a few of our notifications to make sure we've got everything worked out, and then the plan is to roll it out across all of them.
