Dynamically load color scheme data as needed

[GoogleCodeExporter]

I knew it couldn't be that easy. :)

The method described above shows how to create a new script element and append 
it to the head element. This 
is a fine strategy, but does not tell us when the script file has *fininshed* 
loading, which we need to know so we 
can draw (or maybe redraw) the graph.

The method described here is more complete:

It creates the script element to load the JavaScript file. The file ends by 
firing a custom event, which we listen for 
to know when the file is done loading. Firing a custom event is new in 
Prototype 1.6, so we need to update our 
Prototype. I filed issue #21 to do that.

Some time between 2.21.20081029.0445 and 2.21.20081115.1321 Graphviz started
automatically translating color names to their hex values in xdot output. I had
requested this here:
https://mailman.research.att.com/pipermail/graphviz-devel/2008/000792.html

Thanks to this change, the color scheme files aren't needed anymore for current
Graphviz. But I still want to implement dynamic loading to best support older 
Graphviz.
