Make GridTools::delete_duplicate_vertices() faster.

This change makes this function, for cube-like geometries, O(n^(3/2)) in 2D and
O(n^(5/3)) in 3D rather than O(n^2) by presorting vertices by value in a single
component and then only comparing vertices which are nearby in that component.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
