Fix Object::notification order

Browse Source 
Previously the `p_reversed` parameter didn't influence the order
in a correct way.
Also script overridden _notification functions were not called in
the correct order.

To fix this some `notification` functions had to add a `p_reversed`
parameter.

This made it necessary to adjust cpp-bindings.
