committing a change that eliminates the avisoexternal module from the server.
Now, the FSM generation code is moved into the server core instead of being
a call to two scripts via a tmp file.  The ranking code is in the avisomodel
module.

The remaining external code is the correct model generation code and I plan
to move thta into the server core in the same way.
