Orange: daily noodle updates;

- Texture Node: now displays 'intensity values' in node too, and has input,
  and shows in buttons when activated in Node editor. (no browsing buttons
  yet...)

- New: "Normal Node". This uses a new UI button, which allows to quickly
  input a normal vector, based on spherical coordinates.
  The Normal Node has optional vector input, and delivers a dot product
  then. This can be used as a blending factor between nodes, or for fake
  extra light in a certain direction.

- New: "Geometry Node". This actually replaces the Input node. It offers
  all coordinates (vectors) as being the starting point for shading and
  for textures. Note: for preview render this doesn't give much different
  results yet... this is the start for real render support!

  The two new nodes in action

- Bugfix: the "Block" button (which delivers popups) did not return a
  correct event when nothing happened (mouse moved out), which could
  cause mouse clicks to be passed on to the queue.
