Hide answers and comments tab on public user page

There's no real reason why normal users would want to see all answers and comments from another user, but there can be negative side effects (vote manipulation, mainly). Let's hide the overview (useless either way), answer and comments tabs from other users that are not admins. The documents page could be useful in my mind, because if someone e.g. creates really good summaries, you might be interested in seeing the other documents of that user. Since there are no downvotes on documents, this should not open any avenue for mass downvoting or similar.
