Make permissions preference page work again
Add german label for "Anwender->Ansicht" preference page

Until now just an empty label was shown.
Adapt PatientenListeView properly when user changes

Up until now, if the PatientenListeView was visible before login or when
the user changed, the user's settings for which fields should be visible
were not applied properly.
Make focus field in DefaultControlFieldProvider configurable

Before, the focus would always be set to the first field.
Select one of the user's mandators on login

This was broken, especially if the user is assigned multiple mandators
but not all of them. Now it will just chose one (the first one) of the
user's mandators
