Make the reflective emf property setter handle only the properties of the current binding, not the whole hierarchy

Currently AbstractComplexEMFBinding when traversing a binding sets all the properties of a given EObject. This contradicts the bindings semantics as does not respect the bindings execution mode (OVERRIDE/BEFORE/AFTER).
So make it so it does respects the execution mode.
In principle, all that really has to change is "getAllEStructuralFeatures()" -> "getEStructuralFeatures()", though care shall be taken that most bindings that are relying on the default OVERRIDE mode could break, which should be solved by setting the proper execution mode.
