Update all localization dependent objects that this managed object can reach,
except for its aggregated children (which will be updated by the Core).

To make the update work as smooth as possible, it happens in two phases:
<ol>
 <li>In phase 1 all known models are updated.</li>
 <li>In phase 2 all bindings are updated.</li>
</ol>
This separation is necessary as the models for the bindings might be updated
in some ManagedObject or in the Core and the order in which the objects are visited
is not defined.
