feature 2559: minor redesign on configuration screens

* hide "rate_anonymous" when "rate" is deactivated
* hide "email_admin_on_new_user" when "allow_user_registration" is deactivated
* move history settings on main tab
* turn the 3 lines for history into a single line with 3 checkboxes
* for comments, turn the "notify admin" settings into a single line with 4 checkboxes

TODO: remove obsolete language keys
