Update examples to use XmlListModel from QtDeclarative

Now when the XmlListModel is a part of QtDeclarative, we
can udpate the examples, which were using the model.

This patch introduces the following changes:
- Uses XmlListModel from QtDeclarative, removes the custom
implementation from shared subdir.
- Improves photoviewer and rssnew examples to get rid of
some qml and C++ warnings and deprecation notifications.
- Updates the documentation for photoviewer and rssnew
examples to reflect the usage of the XmlListModel from
QtDeclarative.
- Enables documentation build for rssnews example
