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).
Apparently, the form_spam_protect plugin only works with HTTP POST, not GET.
Unsafe operations (save and file-upload) should be POSTs anyway.
Fixed.
Also, two broken tests fixed. Only two Unit Tests now fail: both are minor bugs in XHTMLDiff.
