Support ColorBrewer color schemes

[GoogleCodeExporter]

Support all the colors listed here:

http://graphviz.org/doc/info/colors.html

We currently only have the X11 color scheme in gvcolors.js. Should probably put 
the ColorBrewer 
colors into a new JavaScript file brewercolors.js rather than including them in 
gvcolors.js, so 
gvcolors.js doesn't get too large.

There should be an automatic way to convert from lib/common/brewer_colors to 
brewercolors.js, 
via a script. Implement #1 first, but the format of brewer_colors is different 
from the format of 
color_names so it will need a different script.

Note the need to include their licensing verbiage in our documentation.

As of r104, gvcolors.js is called x11colors.js to better reflect the name of 
the color scheme contained in the file. 
In r106 I added brewercolors.js and the scripts that generated it, but you 
can't exactly use it yet because the 
colors in brewercolors.js and x11colors.js overwrite each other.

As of r110, color sets no longer overwrite each other.

The ColorBrewer license was added in r139.
