The "removed" argument of the models "items-changed" signal was
forgotten making it misbehave when origins do get removed:
GLib-GObject[1287799]: WARNING: invalid (NULL) pointer instance
GLib-GObject[1287799]:CRITICAL: g_signal_connect_object: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
We add a small hardcoded table for now. Future versions
will improve this to parse this out of ASOPs eccdata.
If we can't determine the type of a number we add it verbatim.
