Ride Plot Highlight Interval on Hover

.. As you mouse over the ride plot it will now highlight
   the shortest interval that that point is within.

.. If an interval has been selected in the sidebar it will
   refrain from hover highlighting as it is distracting

.. Also fixed up the way the highlight curve works so it
   has its own axis and works regardless of the data series
   selected.
