Support for custom fonts missing

[Gruber]

Hey there, first of all thank you for this amazing tool! 😄

I was wondering is it possible to copy snippets retaining webfonts and iconfonts used? Simple test case, I went to Fontawesome page and tried copying home main features section, with this result http://codepen.io/Gruber/pen/EVaaMm.

I guess I'm asking something quite hard to achieve, or maybe I'm just blind and missed something obvious of your great tool! 😉
