==================== Summary ====================

Name: Tools-mt.566
Author: mt

Ancestors: Tools-mt.565

Established a dependents-replationship between list item wrappers and list item morphs to support partial model updates.

Added support for the #contents model update in list item wrappers. That is, tree models may now update their children and notify about this. The whole tree view/morph does not have to be refreshed but only parts of it.
