Thiemo Kreuz 0ba7480901 More complete top-level part selection support in new sidebar
This comes with a few significant changes:
* A whole bunch of places in the code that focus and highlight
  an element in the old sidebar consider the new sidebar now.
* Same when e.g. the toolbar at the bottom needs to know which
  part is selected. This is read from the new sidebar now.
* To make this possible I had to merge the small helper class
  we introduced in I7bc73cc back into the dialog.

It's helpful to understand how the event flow works:
* You click a template name. This does nothing (does not select
  the element). It only triggers an event.
* The event is catched by the outer container that manages
  all parts. From there all elements are unselected, and one
  selected. This call is internal and should not trigger
  another event.
