Describe the update

This pull request contains several fixes and updates to the carbon simulation to (1) reproduce carbon species in the GCClassic standalone CH4, CO2, and tagCO simulations and (2) ensure consistent results between the carbon simulation in GCClassic and GCHP.

Expected changes

These changes impact only the carbon, CH4, CO2, and tagCO simulations and do not impact the full-chemistry benchmark simulations.

…mbustion emissions

The emission for GHGI_EE_COAST_OTHER_MCOMB in HEMCO_Config.rc.CH4 was incorrectly
assigned a hierarcy of 100 (added to regional US emissions) when it should
have been 1 (added to EDGAR global emissions). The wrong mask was also applied
to this field - it should be 1009 (CONUS_MASK_MIRROR) and not 1008 (CONUS_MASK).
These typos caused mobile combustion emissions to be double counted over the US.
The typos were not present in the HEMCO_Config.rc files for carbon simulations.

Also made other white space and comment updates to HEMCO_Config.rc files
for the carbon and CH4 simulations to ensure consistency between the two
simulations.

…n against carbon simulation

The carbon simulation currently uses GFED biomass burning emissions by default
(for all carbon species). It also uses GEOS-Chem v5 OH which is currently
required for CH4 in the carbon simulation. To simplify validation of
the CO in the tagCO simulation vs the carbon simulation, we update the
HEMCO_Config.rc.tagCO to use the same options.

Also made a minor change to the OCS biomass burning diagnostic name for
consistency with the other carbon species.

This update prevents printing a message every timestep intended only to
be printed once.

The activate flag is needed in the transport menu since it is used to set
Input_Opt%LTRAN. This update fixes a bug that caused mixing ratio update
with pressure ratio every timestep.

…lassic

The scale factor is removed from HEMCO_Config.rc since the conversion
happens automatically in HEMCO read for GC-Classic. For GCHP the scale
factor is now configured in ExtData.rc.

All emissions for OCS are surface so total can be 2-dimensional rather than
3-dimensional.
