Change date format to follow traditional format

On WoP, the date format follows the format YYYY-MM-DD when you hover over a date.

This is confusing when you are used to dates before months. Months and dates can easily be confused.

The current order is mostly seen in international contexts, unlike what WoP DK is.

Instead, I suggest using the format dd.mm.(yy)yy or similar. At least something with the DMY order.
