Fixed in both branches. (I hope.)

The problem was that a property node was addressed by its path at
a time when the tree was already partly destroyed. The fix was in
my copy since a long time, I just forgot to commit it.  ;-)

Most features aren't "necessary", but there's a reason why they are
there. That property is meant to attach listeners, so that Nasal
scripts can get a hint whenever a model is added (/ai/models/model-added)
or removed (/ai/models/model-removed). Something like that was
requested by people who work(ed) on Nasal-based Radar implementations
or the chat feature.
