Convert WOFF Fuel UX font to base64 and store in CSS file.

@futuremint We can do the same with BS3's glyphicon font, but that will probably be a rucksack issue @kevinparkerson.

From what I can ascertain from Chrome Timeline. The base64 decode may be adding 10-20ms to rendering time (It's within multiple reload margin of errors though).

Right now, initial network download from Akaimai of WOFF file ranges from 225ms to 900ms (although I am on a plane right now with pretty bad latency).

HTTPS requests from Akaimai are taking 500ms to 1.5s (but then again, I'm on a plane).

We probably shouldn't be encoding large fonts, but this small one seems like a good idea for optimization.
