* Better abbreviation modes for layer names in pane (and input model combo
of plugin parameter dialog)
* Avoid crash when loading SV file containing model derived from nonexistent
model (shouldn't happen of course, but see bug #1771769)
* Remember last-used input model in plugin parameter dialog
* Don't override a layer colour loaded from a session file with the generated
default colour when attaching it to a view
