Guess what? Topic URLs are done already

This is the proper 0.1 release.
Again, please install the base package first, rename example.htaccess to .htaccess (edit it if you want to) and then install the ext-none package. Enjoy.
[Edit] Just installed it on my 30907 posts, 1332 topics forum, and it seems to be working perfectly! I was worried it might time out PHP, but it would probably only do that on huge forums.
