Provide input formats for DateField

The datepicker in Materialize will put dates in different forms into the form field. Thus the following input formats must be set (maybe other, too):

forms.DateField(input_formats=["%m/%d/%Y", "%d.%m.%Y"])

added part::frontend prio::2 type::feature labels

I think, this isn't a problem anymore since the datapicker is localized accordingly.
