[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [56590] trunk/blender/release/scripts/ modules/bpy_types.py: Removed the unused socket template system from the bpy_types Node base class (it interferes with the input_templates/ output_templates functions from C nodes).

Log Message:
-----------
Removed the unused socket template system from the bpy_types Node base class (it interferes with the input_templates/output_templates functions from C nodes). This can be reimplemented in a nicer way for pynode subclasses later on, but should not be part of the basic Node class.
