AWSM daily running 1 more hour than needed

[scotthavens]

In awsm_daily_airflow the end date is 24 hours from the start date meaning that the next day's folder will be created with one value in it (for the 00:00 time). Changing it to 23 hours would make it stop after completing the 23:00 run and not make a new day.

This does not have any affect on how the model runs as the value will be recalculated for the next day, making the 00:00 hour calculated twice.
