Making detectors with mesh movement *almost* safe in parallel:
 * Adding test case detectors_mesh_movement_parallel where fixed static detectors go across parallel boundaries
 * Added a second picker_inquire call to search_for_detectors that will search the Halo if necessary
 * Calling distribute_detectors after re-synchronising physical and parametric coordinates so that detectors found in a Halo will be send to the according proc

Note: If the the virtual detector displacement due to the moving mesh is greater than the Halo bad things happen, which will be fixed soon with a broadcast.
