Clarify the documentation regarding QDeclarativeListProperty and ownership

The documentation for QDeclarativeListProperty and ownership is not clear, it is implied that the ownership of the contents of this list will be Javascript if the QML calls a function that creates the objects and populates the list that is returned.

Generally having an example and more clear documentation on how to use this class correctly would be good.

I have attached the example I used to illustrate this, the fact I have to do:

myObject.getInfo = [];

to get it to clear seems to indicate that it is not owned by Javascript.
