[Bf-cycles] Remove old Sky Model

[Thomas Dinges]

Hi,
I reverted the commit now, so the Preetham Sky Model will still be 
available for the duration of 2.7x.
I apologize for the inconvenience, I should have communicated the change 
better beforehand.

For the 2.8x series of Blender, we can re-think this (and other things 
too), but best to make a list of changes first and discuss it.

Best regards,
Thomas
