Cleaned up the email notification of comments with a number of features that should make it more useful. First, the comments now appear to come from the email address of the person who left the comment, so if they filled it in you can just click reply in your email client to respond privately. Second, the name of blog is now in the subject, which should be very useful for those who run multiple blogs. Third, slashes are now stripped from the email subject. Finally, the message text has been cleaned up with capitalization, the name of the post, a real link to the comments (using comments_link), and a handy whois link. I also started the tedious process of fixing the template functions so they don’t necessarily echo out, they can return as well.
