Modified TimeSeries to set the timeRange property from the retrieved
data if the time series is created without the timeRange property. 

Modified GraphPopup to adjust the x axis using the timeRange from the
visualization (which is the correct way to do it anyways).

Made other visual tweaks including descreasing the padding between the y
axis label on the load plots and making the MRB load popup longer.
Reverted the change which shouldn't have been committed.
