Bugfixes and Rails Edge

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).
