This brings us up to the latest FontAwesome 4.x release, allowing us to

make use of a number of icons we previously didn't have available. We're

on 4.7 instead of 5 because 5 is not backwards-compatible, and would

require more extensive work that's not appropriate for a point release.
Instead of simply bundling the minified CSS file and fonts, we're now

shipping a version-namespaced set of LessCSS files and a wrapper

fontawesome.less that imports from the namespace. This will allow

other stylesheets to reference variables defined in the LessCSS files

(such as icon name) and mix things in. The namespacing helps us keep

that wrapper file's name consistent while helping us manage upgrades.

Looked throughout the product for places where we use FontAwesome icons.

I didn't see any breakages.
Tested the new consent UI (which uses newer icons) and saw that they were

properly loading (which wasn't the case before).
