Overriding flot legend
Added settings constant to set the current water year. Modified
PlotUtils to use this value rather than calculate the current water year
from the actual date.

Also fixed an issue in the mississipi graphs where 2013 data was not
being shown because it uses a separate modtype and we were only fetching
the one series.
Adding a second to the endTime in the temporal filter so that data at
endTime is retrieved.
