Improved the accuracy of the plot so that the solstices and equinoxes fall on the most likely dates: March 20, June 21, September 22, and December 21.

Also fixed it so that number of daylight hours reported when clicking on the equinox events will always be 12 (in earlier versions this wasn't working at latitudes of +-90).
