Add the "Auto Levels" feature from RT

[caugustin]

Hi,

I find the "Auto Levels" feature of RT (under "Exposure") quite useful and would love to have it back in ART. It does a good job for a starting point in my opinion.

Hi,
Thanks for the feedback. The whole exposure module has changed quite a bit under the hood though, so it would be hard to implement this. If you want something automatic, did you try the automatched curve?

Hi,
I see, sounds like too much work. Automatched Tone-Curve does not work for me, since there are no embedded previews in my raw files (at least not in those I'm working on at the moment, which come from an iPhone app). Auto Levels did work in those cases.
(I just tested with other raw files that does have previews, but Automatched Tone-Curve does not seem to have any effect; no "comprehensive" test, though.)
