Feature Request: Allow Sass Output or Allow output of css unicode classes

[resonantbreath]

I want to import this file into my project which uses Sass, and sass is fast becoming a standard in web development. I want to express my interest in having fontcustom output sass file or even just allow me to only get the outputted css class names like:

.icon-expand-up-arrow:before { content: "\f100"; }

without the bootstrap css being added.

Thank you for your development effort!

No problem — I'm working on this today. Closing, because this is a dup of #59.
