binder_ew nucleates more events in v7.10

This was discovered at Caltech and I have found a bug in grid.c that needs repairing. I have already fixed it and tested it at Caltech and on some internal ISTI projects. We put this in play at Oviedo too. It is urgent that people stop using the binder_ew that came with v7.10 and use this new one or revert to the one that came with EW v7.9.
