rename need_navigation into paginable paginable has been recently introduced by changeset d4eeaf0393e2. We already had the need_navigation attribute to control the same thing (pagination). As paginable sounds like a better name, deprecates need_navigation (bw compat ok). Also: * fix main pagination functions responsability * deprecate limit_rset_using_nav in favor of paginate/do_paginate * navigation module should be renamed to pagination at some point

"""pre 3.2 bw compat
