GtkAccelLabel: adjust recent accel changes

Browse Source 
In the event that a GtkAccelKey was present for the closure but it
contained a keyval of 0 the previous code would show "".  After the
recent adjustments, "-/-" would be shown in this case.

It turns out to be a pretty common case, so fix the logic to stop using
'0' as a magic value to mean "don't have an accel" and add a separate
boolean for that purpose.
