Style name unknowable to non-Pythonistas

[PhilHudson]

First off, thanks for taking the time to do this and make it available as free software. Now the issue: Nowhere in your doco or setup procedure am I clearly informed that I have to use style name "solarized_dark256". I only found that by spelunking through code and setup diagnostics until I came across something that looked like it might work. Which it does, now, thanks again: best solution out of several I've tried for getting 'less' to syntax-highlight Emacs Lisp code in a terminal emulator. So please add that crucial detail to your README.md.
