Nawqaan 377

These changes have little to do with NAWQAAN 377 but do fix issues with data visualization for the loads. Specifically, current water year is now set in the settings.py and added to the CONFIG object on the client side. Also fixed the issue with the Mississippi load plots not retrieving the second time series data and fixed the issue with missing 2012 data in the load plots on the detail page.

Once reviewed, it can be merged. Put NAWQAAN-377 back into implementing and assign to me.
Thanks for documenting that assumption.
