Ext.tree.MultiSelectionModel selectNext()/selectPrevious()

[rad_nq]

It seems that Ext.tree.MultiSelectionModel does not yet implement selectNext(), selectPrevious(). As a result when you try to use the arrow keys you get exceptions.

To work around this I ended up patching it temporarily by copying and pasting the method from DefaultSelectionModel.
