Initial commit of a flot plugin that allow data series lines to be
dashed.
Added new library for dashed flot lines to the mississippi page and
updated CONFIG with the url used to fetch the baseline, target, and
moving averages for a site and constituent pair.
When creating a time series visualization object, it now takes and
optional averagesAndTargets property which is an object containing the
mean, target, and moving averages for that visualization.
When creating the load graph, fetch the averagesAndTargets to be used in
the visualization.
Added code to draw the baseline, target, and moving averages if
available on the LoadPlot.
Fixed a couple of typos, unused code, and comments.
Moved the milliseconds in year to nar.utils and changed the comparison
to the empty object
