1) Bugfix: changed INNER JOIN to LEFT JOIN to make forum topics with no comments show on the topic overview page.

2) Beautified the forum module views; rewritten to use the table() rendering functions, X HTML-ified the emitted code, added additional CSS tags, and removed hard-coded markup.  This improves themeabality; it should be able to mimic the view and color scheme of, say, http://www.phpbb.com/.

3) Reorganized forms and links (interactive elements) to improve usability.  Also ensured that the link names and page titles match.

4) Temporary removed container functionality: this simplified the work and eliminated some usability issues.
