idNumbers now are only editable from the admin page for each user.
We should keep the editing opportunity there, although the users should be able to edit there idNumber from their profile page as well.
Disable all regex frontend validation of these fields (on the old spot too), because non-hungarian idNumbers (with different formats) caused some trouble last time.
Create a more sophisticated look for this field on the admin page. (Maybe it should be disabled by default and only be editable with the push of an edit-pencil icon, idk)
