datepicker: Fixes regression in #3232 [datepicker position problem in IE 6/7]: added back functionality to detect whether the datepicker displays outside a viewpoint. Additionally if the viewpoint is too small to fit the datepicker it will show in its usual position regardless. I have also added a visual test case for this.
