Clean up setting estim_params_ as global

In line 675 of ModFile.cc we set global M_ options_ oo_ estim_params_ bayestopt_ dataset_ dataset_info estimation_info ys0_ ex0_ But in line 1031 of ComputingTasks.cc we again set estim_params global if an estimated_params-block is present: output << "global estim_params_" << endl I would get rid of the latter statement and only keep the one setting all globals global.
