Orange: more Node goodies;

- New Node: "Mapping". Allows input vector to be translated, rotated and
  scaled. And optional be clipped to a range. Works for colors too!

- The button "Normal" now allows incremental input, so a click in the
  button won't change the normal anymore

- Connecting wires now show selection state for Nodes, with nice blended
  colors. Both colors were added in Themes, but default to black and white
