Rearchitect handling of Font Awesome

[david-poindexter]

Is your feature request related to a problem?

Right now Font Awesome is preloaded in the dist folder (fonts and CSS). The build process should simply pull precompiled CSS and fonts from node_modules. This will allow us to properly manage Font Awesome package dependency appropriately via package.json.

Describe the solution you'd like

Add new fa-init Gulp task to copy Font Awesome from node_modules to dist and add to build task.

Describe alternatives you've considered

n/a
