 Flickable:
    - overShoot is replaced by boundsBehavior enumeration
    - flickingHorizontally and flickingVertically properties added

 QList<QObject*> models no longer provide properties in model object.  The
 properties are now updated when the object changes.  An object's property
 "foo" may now be accessed as "foo", modelData.foo" or model.modelData.foo"
