Add remesh modifier (dual contouring).

This patch adds a new remeshing modifier. The algorithm is based on
the paper "Dual Contouring of Hermite Data", and the implementation
was contributed to Blender by Dr. Tao Ju.

The contributed code is in intern/dualcon, and was modified to compile
under gcc and work on 64-bit systems. Files not needed for Blender
were removed and a small C wrapper was added in order to interface it
with Blender. The rest of the patch is just standard modifier stuff.

The remesh icon was contributed by Zafio:

Thanks to everyone in that thread for the icon proposals and
discussion.
