Interface List: Change display to view/model

This changes the underlying model of the main interface tree.
Because of that, we can resort to a view/model approach, enlisting
the global interfaces list as only data source.

The interface list works identical to the old list, but allows
for filtering of the displayed interfaces by type. Only types, which
are present and whose interfaces are not hidden, are being displayed
for selection.
