Title: Removed usage of model class Contacts from drop interface

According to the model-view-controller concept, the Contacts class
should not be exposed in the drop interface.
Instead, a collection of "Contact"s is used.

I remember that @Gottox raised this issue somewhere, but I cannot find the context.
