Comments counter and all button
small text fix
Fix all comments link for guests

The jquery selector was depending on the comment form to be there.
Logged out users don't have a comment form and therefore, clicking the
"All Comments" link resulted all comments being removed from the DOM.

The fix adds a .comments div inside .Comments-section so that there is a
proper section containing all the comments.
