Use the new CalendarDate in some document types

From 11 we have a new field type in the doctype editor: CalendarDate, which does not have time fields, but only shows y-m-d. We can promote that field by using it in some document types in Essentials.

In some types having the hours/minutes there seems appropriate (News, Events), but I think we should replace the Date field with a CalendarDate for Simple content and Blog.
