Saving of Metropolis Information

Currently, dynare_estimation_1 calls the metropolis routines as: feval(options_.posterior_sampling_method,objective_function,options_.proposal_distribution,xparam1,invhess,bounds,dataset_,options_,M_,estim_params_,bayestopt_,oo_);

and takes no output arguments. Thus, information of the record-structure of random_walk_metropolis_hastings is not saved. We might want to store that information in the future, see http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=4462
