Maik Justus,

Maik Justus,

Here is a patch for two bugs in the AI/multiplayer part:

1. Cannot find model file *.ac error message (was only a false message,
anything worked correctly, the model was loaded from the correct path
afterwards).

2. Often many multiplayer aircrafts are missing in the property-tree.
(but I need them for aerotowing). There is still another bug: The
property in some circumstances seems not to be cleaned up after logout
of a multiplayer. I have added a workaround for this, but I don't now,
if it 100% works (should have no side effects, just aerotow would not
work sometimes). For testing I need more traffic on the mp-server.
