levelset: fix evaluation of levelset for surfaces that contain pixel elements #376

Connectivity of pixel elements does not list the vertices in anti-clockwise order. This needs to be properly taken into account when flipping the normal and when evaluating segment information.

I've added an additional fix for the hash operator of ElementHalfItem.
