First display year on datepicker component

Hi guys,

I tried to edit the calendar that appears in the registration form so that users can more easily select your birthday . The idea is to initially show the year , then the month and finally the day . As I read enough with edit the file ../media/foundry/4.0/scripts/ui/datepicker.js in line 71

change...

showMonthAfterYear: false, // True if the year select precedes month, false for month then year

for

showMonthAfterYear: true, // True if the year select precedes month, false for month then year

but I can not see the change. any idea how to do it ?

Thank you very much !
