After this change, the parent properties of model nodes do not have
to be "data" or "children" anymore. Any node or node list property
can contain children.

I did some changes to the patch.
1.) Fix for NodeMetaInfo
2.) Remove changes to ObjectNodeInstance
3.) Adapt QmlObjectNode

Avoids problems when e.g. running 'make clean' - this one tries
to delete all files named core.

This function returns the expression in a certain state

This patch is eliminating the switch from the state the base state and back if a property is changed.
 For that it is updating the internal caching values in QDeclarativeState.

This adds a new "Design" mode that can be used to manipulate qml files
in a visual way. It will only get build if you have the declarativeui
module in Qt.
