prune-trace: --no-weighting for SamplingPruner

Browse Source 
Analogous to the FESamplingPruner, the --no-weighting switch disables the
equivalence-class weighting by using a weight of one instead of the
equivalence-class size.  This is usually not a good idea, and should only
be used for demonstration purposes, or if the fault model requires
weight-less sampling.

The --no-weighting switch was introduced with an earlier commit, but
did not have an effect until now.
