* Source/NSToolbarItem.m (-_isFlexibleSpace): Simplify this method.
* Source/GSToolbarView.m: Clean up toolbar item resizing, this now
allows for resizable item other than flexible space.
allows for resizable item other than flexible space. If there are
flexible items and flexible space the items will be expanded first.
