Change the default color of circle and ellipses, etc. back to be the same shade of blue as for all other graphics objects

We'll have to check how to keep the colors black for the default wherever this is used in graphs, unless it shouldn't be.

Okay, I ended up making some doc prettier and adding graph plotting to the reference manual (although it's added to two .rst files, there is only one additional html file created in the manual). I believe that this correctly addresses the original problem while keeping graphs looking the same, but I'd appreciate any reviewer really comparing the "live" doc for a significant number of plotted graphs in the reference manual.

Looks good to me. Test pass. Lots of plots I plotted look good, etc. And I like the patch.
