Subject: Render API: shader script node for custom shaders.

* Shader script node added, which stores either a link to a text datablock or
  file on disk, and has functions to add and remove sockets.
* Callback RenderEngine.update_script_node(self, node) added for render engines
  to compile the shader and update the node with new sockets.

Thanks to Thomas, Lukas and Dalai for the implementation.
