Gimp/app/widgets/gimpcontrollerlist.c
Michael Natterer aea5e7ec9e app: implement GimpContainerListView, using a GtkListBox 
It completely relies on GListModel and doesn't manage any list items
itself. The port should be pretty much feature-complete.

Add a ton of stuff to GimpRow in order to look and behave like a
GimpContainerTreeView row.

Add a playground switch to use the new widgets in all views that can
be switched between list and grid view (brushes, patterns etc.)

Please test!
