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).
