Fake EdX view, UI Library refactor, add FontAwesome icons

[ryaanahmed]

• Creates a fake edx component to render our apps into, so we can see roughly what we'll look like in context

• Adds a UILibrary folder, which contains:

  • AllView that renders everything, so we can look for design inconsistency across the project, and is where Luke will put a visualization of our design system
  • components.js, which is where we'll put bits that are reusable across the system

• Adds FontAwesome icons to the project (mostly for the fake EdX thing, but still useful)

Looks great @ryaanahmed -- will start on the ui_library branch today.

Great, merging. @lukehollis -- I'll start an issue where we can discuss typography, etc. Basically we should try to unify with edX as much as possible, so that our apps look consistent with the rest of the site.

Super good for visualizing the use in the system!
