use_default_fallbacks

Whether to use the default fallbacks found by shortening the icon name at '-' characters.

If the "names" array has more than one element, ignores any past the first.

For example, if the icon name was "gnome-dev-cdrom-audio", the array would become

{
	"gnome-dev-cdrom-audio",
	"gnome-dev-cdrom",
	"gnome-dev",
	"gnome",
	NULL
};
