Todo list for forum code

• HTML needs to be properly sanitized.
• BlueCloth won't work here because quoting is formatted into blockquotes. An odd situation because the philosophy is the same. so...
  • some of BlueCloth ought to be integrated bold/italics/underline.
• While topic list is sorted descending on create date, it might be better to sort it by the last posts date. That way old topics are bumped to the top if someone posts on them.
• Anchors should probably be used in rendering topic threads keyed off post_id, so recent posts and rss can take one into the thread to the post, rather than a single post page.
