                vitalets: fixing bug of very special conditions:
                jquery 1.7.1 + webkit + show inline datetimepicker in bootstrap popover.
                Method show() does not set display css correctly and datetimepicker is not shown.
                Changed to .css('display', 'block') solve the problem.
                See https://github.com/vitalets/x-editable/issues/37

                In jquery 1.7.2+ everything works fine.
