CVS commit by harris: 

More improvements to solar system tool:

+ Time can now pass in the tool, so you can watch the planets move.  You 
can set the date, and there is a timestep widget for adjusting the clock 
speed (the minimum timestep is 1 day), and there is a "play/pause" 
button. 

+ The data for plotting planet orbits is now stored in *.orbit files in 
the data directory, so we don't have to recompute them every time we 
open the tool.  This eliminates the init lag completely.

TODO:  
- add ability to run the clock backwards
- centering on a planet should engage tracking
- Pluto has problems.  If you let the date go past 2125 or so, it starts 
a catastrophic deviation from its normal orbit, doing totally 
non-physical looping motions.  By 2300, it is leaving the solar system 
completely.  I suspect the code I used for pluto's position is only good 
for dates near the present epoch; I may just make Pluto a KSComet object 
and use the JPL ephemerides...(please no holy wars!)
