* 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
