I suspect that work around for the /ai/models/model-added listener problem
(i.e. that the listener is called in the middle of the process of
adding/removing a MP entry) isn't the right way to solve the problem.

The attached patch instead defer processing of the added/removed
MP entries in the multiplayer Nasal module until the next time the Nasal
subsystem is executed. This should prevent the problematic execution of
the Nasal listener callback in the middle of C++ MP code.
