Fixed #18767 -- Fixed admin calendar for other locales than English.

Refactored openCalendar function from DateTimeShortcuts.js. Now, when
entered manually in the input field, the date will show up correctly on
the calendar for locales that don't use "-" for separator.

Thanks charettes for revivew and Alexey Boriskin for some of the patch.
