Title: Modify the Layers'opacity slider behaviour

PR : https://med.inria.fr/redmine/issues/1737

This slider is currently a bit hard to use. I don't think it makes the job.
So I modified it a little bit according to what I think he should do.

The best way to test it is after a paint segmentation.
