(Fixed) Missing buttons/icon

In the latest build (jan-18),
The outlines of the manipulator "Set" buttons and the icon for the "Workplane manipulation tool" are missing from the manipulator window.

On a quick check, I also see that the visual tools button outlines are missing from the non-visual style buttons (and they no longer highlight when moving mouse over them). I have not checked the other windows.
