Title: Base source rupture-site distance filtering uses Joyner-Boore distance

Addresses https://bugs.launchpad.net/openquake/+bug/1036243

Note that even though this is independent from https://github.com/gem/nhlib/pull/52 it requires optimizations on mesh-to-mesh jb distance calculator side for good performance.
