Open notes in new window, instead of printing to console

It can be tedious to load up the speaker notes, with the whole having to
open the javascript console, and clicking on the link.

This simplifies it by automatically opening the notes in a new window.
Most browsers will warn that it's trying to open a pop-up, but it's easy
enough to allow it.
Support markdown in speaker notes

It's pretty nice to have markdown in slides. It's even nicer to have
markdown in speaker notes too :)
Add documentation for markdown speaker notes
add rvl.io to readme and template slide
