Fix hide items in HypreTreeList

Browse Source 
Hiding items was only partially implemented and very buggy.
This feature does not exist in CustomTreeCtrl but I see no reason why
it couldn't be added in the future. This fix requires the arrow key fixes
in order for arrow keys to work reliably in a tree with hidden items.
Hidden items always report they are disabled and not expanded.

Also updates the demo of HyperTreeList to add hide options to context
menu so the feature can be tested.
