I tried to stick as close to the existing code as possible.
Special:Notifications is slightly different from the overlay,
however. I made it add .mw-echo-unread class for consistency,
but that JS doesn't record seen time (it only loads older
entries), not does the CSS fadeout apply there (it marks
everything as read as soon as it's displayed, so different
behavior from overlay)
PS: I'm not sure about browser compat for the fadeout. But
even if some obscure browsers don't support this, meh. It's
not an "important" feature that can't be missed.

To test the HTML email:
1. install the latest version of php-mail and php-mail-mime package, they are required
by the core sendmail function to send HTML email
2. set $wgAllowHTMLEmail = true before loading Echo in LocalSetting.php
