[Qt-qml] PathView/VisualDataModel bugs

[Girish Ramakrishnan]

I went on a little bug reporting frenzy today. At this point, I am
thinking maybe I missed something in the docs or all the bugs are
probably interrelated. Someone has to double check the reports, but
until then, I wanted to just give a heads up that one shouldn't mix
PathView and VisualDataModel.

QTBUG-16366 PathView/VisualDataModel - currentItem is not updated when
the rootIndex changes
QTBUG-16365 PathView/VisualDataModel displays nothing with Tree models
QTBUG-16357 PathView does not work if VisualDataModel is used with a
model that is defined outside the VisualDataModel element
QTBUG-16356 PathView crashes at QDeclarativePath::pointAt
QTBUG-16347 PathView does not have currentItem property

Also,
QTBUG-16360 ListView does not show all items with
VisualDataModel/QFileSystemModel
