Support TemplateLiterals and quotemark option.

I had originally filed this to solve issue #1797. This solves the problem for me, but I think checking the value of data.quote inside of style.js  would probably be more correct. If anyone could point me in the right direction of doing so I would appreciate it. We need to populate the data.quote with a ` (backtick) character instead of being undefined.
@caitp - Thanks for the tip. Any chance you could point me to a line where the ```quote``` value should be defined? It wasn't immediately clear to me and I'm new to looking at this code. Thanks!
