Manually changed aveday_N for July 2018 from 20180703 to 20180710
since this is one instance where the logic in the python scripts used to 
create these files differs from the logic in the SMOKE_EMF script
that sets the representative dates (set_days_v5.csh).

Additionally, the python script does not output the correct day-of-week
profiles for the Dec spinup periods. Had to manually edit the 
'mwdss' and 'week' profiles in the 201712.txt spinup file.
