`tryObjectEnter()` and `tryObjectExit()` do not prevent same interactions through searching#778

If a container is searched, we cannot prevent objects being added or removed through tryObjectEnter() and tryObjectExit().

Please could we either add that functionality to the current function, e.g:

tryObjectEnter(object entering_object, bool through_search)
tryObjectEnterContainer(container entering_object, bool through_Search)

or add a separate function for tryObjectEnterViaSearch() and similar.

Reasoning being to allow scripters to fully filter what can enter and leave containers in realtime.
