Try dark color scheme

From information at http://jasonwryan.com.

* New xterm colors in .Xresources
* Use jellybeans color scheme

Jason created his own colorschemes which line up nicely with the xterm
colors provided.  However as of right now they do not work in gvim.  And
I think I like jellybeans better.

http://bytefluent.com/vivify/ is a great reference for vim colorschemes.
