Comments should now properly refresh on Firefox 1.5rc2 (also fixed for any other browser that was deciding that $('commentList').lastChild means the smattering of whitespace between a closing </li> and the closing </ol>)

Also turned off the html filtering for comments which was acting as a “make ugly” flag. (BlueCloth seems to be finicky and difficult compared to Markdown implementations I’ve used before, and RedCloth claims to do Markdown, but didn’t when I tested it)
