Title: Some support to compute avg and std for the GMFs

This is useful when comparing the GMFs generated by two different implementations of the event based calculator, or when investigating the dependency from the random seed, from the number of SES, or some other parameter. See https://bugs.launchpad.net/oq-engine/+bug/1192413. I would accept suggestions for a name better than "moment" for the triple (n, avg, std).
