Updated Instiki to Rails 2.1 RC1 (aka 2.0.991).
Get rid of Redefined CONSTANT warning. Make WEBrick respond to TERM signal. (Launchd, in particular, requires this.) Rollback superfluous change to rails/actionpack/lib/action_controller/base.rb. Handled by the action_cache plugin.
Sync with latest Instiki Trunk (Updates Rails to 1.2.2)
