the ontology's width automatically increases if necessary when expanding
models
changing the ontology's width no longer causes the first model to expand
if it is collapsed
the width of a model (and as a consequence that of the ontology) which
is expanded by dragging its south resize handle is now increased
properly if necessary
fixed a bug introduced by the code that increases the ontology's width
when a model is expanded. Increasing the width when adding entities to a
model now works properly again.
