Faster

Update dnsbl_check plugin to latest version.
Update Maruku to latest version.
In the wiki_controller, only apply the dnsbl_check before_filter 
  to the :edit, :new, and :save actions, instead of all actions.
  This makes mundane "show" requests faster, but does not 
  compromise spam-fighting ability.
