- disabled 'ray shadow' option from UI and render for Hemi lights.

Browse Source 
reason is that raytrace code doesnt like shadow on backfacing faces
  at all. the hemi light is omni-directional, and would need a shadow
  calculation to mimic this as well. the new 'Ambient Occlusion' patch
  will make that possible.
