Resolution limit things

So, I got a complaint from someone who works with membrane proteins, who complained (accurately) that xia2 falls over at the resolution limit calculation step. This was because it assumes a Wilson plot, but this is only meaningful for better than about 4A.

xia2 should now cope - if the data are not there for a Wilson plot calculation it will fail over to a simple hunt for where I/sigma is about 1. Gets it out of a corner here anyway...
