Changed SQL to query against ontario.zonal_demand with
accurate datetimes rather than malformed data in
ontario.Hourly_Demand. The ontario.zonal_demand.total_ontario
column has the same demand readings as ontario.Hourly_Demand.ontario.
Altered the plot function to fall in line with
modifications made to other plot functions.
Adjusted timestamps to take advantage of the
fact that ontario.zonal_demand has 2012 and 2013 data.
