* Merge of PyNodes to trunk. Finally!

See http://wiki.blender.org/index.php/BlenderDev/PyNodes and
  http://wiki.blender.org/index.php/BlenderDev/PyNodes/API
  For current documentation.

  Very very big thanks go to William Germano for fixing the memory issues left
  and for improving on the code.

  In the coming time documentation will be finalised and further stabilising
  of PyNodes is to be expected.
