mothra: make scrollbar style consistent with other applications

	Scrollbar was drawn using a wide dark gutter over a white background
	whereas other applications (window, sam, ...) use a thinner scrollbar with an
	inverse colorscheme.
	This makes the scrollbar more consistent with other 9front applications.
