Overview
reveal-ck relies on github's hosting to reference emojis within slides.
Recently, github must have stopped supporting the paths they used to host emojis on-- they've switched to a new location.
That's just fine-- and I'm surprised it hasn't changed over the past four years-- so this PR supports the new URLs.

This is a fix for #101.
Thank you very much @justin-vanwinkle for reporting.
