Fix saving of posterior standard deviations

When running the MCMC, the
oo_.posterior_mode fields are based on the posterior mode, not the MCMC. But the manual says they should only be there if
mh_replic>0 but we always write them.
oo_.posterior_variance is based on the MCMC. However, this field is not documented in the manual at all.
It is also confusing that the MCMC writes only a variance and ML/mode-finder only a standard deviation.
We must decide on a consistent treatment and fix the manual accordingly.
My proposal is: We change the current
oo_.posterior_std_at_mode to make the meaning explicit and let the MCMC now also write
oo_.posterior_std. This would be closest to what the manual states as all fields then would have the intended meaning while only adding additional fields. If need be, this would also allow going back to the 4.4 "convention" using the
