Title: document/prefer xvfb-run to managing an xvfb process and DISPLAY yourself

Hello! I changed the documentation to use the much simpler (and sadly not as well-known) xvfb-run wrapper (http://www-linux.gsi.de/cgi-bin/man2html?xvfb-run+1). I think this will greatly simplify the process of GUI testing for users unfamiliar with Xvfb, and I'm happily using it on Travis now.

I originally attempted to document xvfb-run and managing your own xvfb process side-by-side, but it felt really complicated and confusing to follow if you just wanted to run a command that requires a display, and I figured that users wishing to manage their own Xvfb server process may not need this guide. I may be wrong, so let me know your thoughts!
