Fixes #76
Atom grabs the color from a gtk menu bar's bg[GTK_STATE_NORMAL] style property (see https://github.com/atom/atom-shell/commit/009e0790fe54f80be15f301336c8bdb251e0b927). Since Iris use an image for the background, Atom doesn't get the correct color. In Iris, setting the menubar's bg[NORMAL] color to the same color as the image has no effect on gtk apps (that I can tell), but means Atom gets the correct color for its menu.
