Upgrade to Rails 2.0.2
Upgraded to Rails 2.0.2, except that we maintain vendor/rails/actionpack/lib/action_controller/routing.rb from Rail 1.2.6 (at least for now), so that Routes don't change. We still get to enjoy Rails's many new features. Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).
