Add variable to switch master pane to right side instead of left side

[hoschi]

Like the 'reflect' layout in XMonad http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Layout-Reflect.html

I have vim on the left monitor of my dual monitor set up ... which is very far left so it is difficult to focus it all the time.

That's a good idea.
