Title: Fixed #8420 - Datepicker: calculateWeek doesn't take firstDay setting into account

https://github.com/ghiculescu/jquery-ui/commit/7741b03a2e191484e1c1a2a6f3a815005dd1f9f1 is the relevant commit. The others are just fiddling around (and then reverting that fiddling) with the rows to show in the date picker, for #8423.

The datepicker should show months like http://i.imgur.com/Y1xGR.png - in this case with firstDay: 0.
