  Log:
  - Fresnel V4.0
  
  Based on feedback (thnx phase!) I found a big disadvantage of the 'real'
  fresnel formula. It doesnt degrade to 0.0, causing 2-3 times too many
  rays being fired compared to the previous one. So; a lot slower.
  
  Now committed is a hybrid which allows (close to) real, and nice artistic
  freedom, *and* it really goes to 0.0 and 1.0, assisting nicely in optimal
  render times.
  A real doc how it works (with pics) will be made before real release.
  
  - Fixed bug in raytrace: the first renderpass didn't use fresnel for mirror.
  - Fixed bug in previewrender, now it closer matches how fresnel renders
