[Jason Harris]

SVN commit 643494 by harris:

New visual Equinox/Solstice calculator module.  Instead of 
displaying the date/time of the solstice and equinox events 
for a given year, the events are highlighted on a plot of the 
Sun's declinatin as a function of time over the course of the 
given year.

Please have a look and let me know what you think; I may try to 
convert some other modules to this "visual" style as well.
