[Ifeffit] Propagation of uncertanties

While we're on the topic...

FEFFIT used to report the uncertainties in computed variables (what 
are now DEF's) in the feffit.prm file. As far as I've been able to 
tell, Artemis doesn't report that information anywhere, and I'm not 
clear if ifeffit still computes it. Is it in there somewhere, and am 
I just missing it? In any case, I would like it if uncertainties in 
def'd variables should be given everywhere that uncertainties in 
guessed variables are given.
