Retinex with chroma and mixed algoritm with Dehaze

[Desmis]

I just create a new branch "retinex_chroma_dehaz"

1) I add a slider "chroma", now Retinex acts on luminance and chroma I copy the work i have realized 2 years ago in waveletnew for Retinex in Raw mode It is not optimzed for SSE

2) I add a slider "Dehaze" which take into account alberto works, adapted to retinex. just at the beginning of Retinex The 2 algorithms works together, Dehaze take into account retinex settings (strength, radius, contrast)

The result seems good (for my point of view)

@Desmis

It is not optimzed for SSE

I will have a look

• The preview matches the output, good.
• Bug in history:
  1. Open photo, enable Retinex
  2. Set Dehaze to 100
  3. Go back in history - the slider changes to 0 but the preview does not change, it still looks like dehaze=100.
• There are hard-coded 200ms delays (in this branch and in dev), they should probably be replaced with options.adjusterMaxDelay
• The language string keys should be changed for readability, DEHAZ > DEHAZE, RETIDEHAZ > RETINEX_DEHAZE, CHRRT > CHROMA, etc. There is nothing to gain by using obfuscated abbreviations.
• Chroma can already be controlled using L*a*b*, dehazing can already be done using the Dehaze tool, so the practical benefit of these is not clear to me. I only have two hazy test-images, so it's likely I'm not seeing the full benefit.
• In one of my two test-images http://rawtherapee.com/shared/test_images/dehaze2.nef , using Retinex > Dehaze leads to haloing around the left edge. The halo does not appear when using Retinex + the Haze Removal tool in the Detail tab in dev,
