Use "fork me" ribbon

Should we use a ribbon, like https://github.com/blog/273-github-ribbons? I checked the other major scientific Python packages I could think of, and the only one that uses it was pandas.

If you just add one of those templates, it goes behind the green bar. So that will have to be fixed. Also, what color should we use? I like how the pandas one is non-intrusive. We should also use something that doesn't take away from the main content. So maybe the white or grey one. Or maybe make our own with a color that matches the green.

Whenever I see a web page with a ribbon, I immediately think that the web page presents toy software rather than serious software. I'm not sure why I have such feelings, it just works for me that way. Thus I'm against using it. However, we can expand development page to include github controls (number of forks, number of watching people, watch and fork buttons). btw. I'm working on a new web site for SymPy since yesterday.

Fair enough. I can see where that comes from. What about SymPy live and SymPy gamma?

I look forward to seeing the new design.

Matplotlib also has one.
