Update to Rails 2.3.1. (Actually, not quite. Doesn't look like 2.3.1 will be released today, but I REALLY want to push these bugfixes out.) Removed bundled Rack (Rails 2.3.1 comes bundled with Rack 1.0). Add config.action_view.cache_template_loading = true to production environment. Fix FastCGI bug (http://rubyforge.org/tracker/index.php?func=detail&aid=24191&group_id=186&atid=783). Fix WikiWords bug (http://rubyforge.org/pipermail/instiki-users/2009-February/001181.html).
