QmlDesigner: Implementing dynamic node properties

Browse Source 
The model now supports dynamic node properties. e.g.:
Item {
    property Item item: Item {
    }
}


In this case Property::dynamicpropertyType() is Item and
Property::isDynamic() is true.

To create such a property I added:
NodeProperty::setDynamicTypeNameAndsetModelNode().

It is not supported to reparent nodes in an out of
dynamic node properties. The model throws an exception in this case.
This is currently not required on the application level and not
supported by the rewriter.
