Foren / Cotonti / Core Labs / Archive / Comments and ratings suggestion

1. always show comments after the article text by default (most visitors don't want to click one more link to see the comments)
2. add "edit comment" function for moderators and admins

same with ratings: avoid separate page, replace standard rating with orkan's plug ( http://www.seditioforge.com/plugins/polls-raitings/one-click-vote-i113.html )
