- when jquery choose the date format,
	it also creates a hidden field with the value formated as 'yymmdd' (Ymd)
- before dfb saves the post queries,
  saves the acf-date of the hidden field into a special property of the acf field
	and removes it from the post-array

- jquery creates a hidden field with the value formated as 'yymmdd' (Ymd)
- before insert post in dfb :
  - find the hidden field, and for which acf field it is
	- save this data in the acf field
	- also save the formated date in the acf field, in a class maybe ?
	- add a filter for the acf field, when it displays the field, to show the formated value
