Updates that will not affect full-chemistry benchmark simulations
Run directory updates for integration tests	Bob Yantosca (Harvard)	Testing	geoschem/geos-chem PR #1794 geoschem/GCClassic PR #41 geoschem/GCHP PR #327
Add sanity check for missing molecular weights; Add missing MW for HgBrO NOTE: This also fixes an issue in the TransportTracers simulation where tracers with undefined MW_g values were set to zero concentrations.	Bob Yantosca (Harvard)	Bug fix	geoschem/geos-chem PR #1843
