Support WOFF files in Celerity and add Source Sans Pro

Summary:
  - Allow Celerity to map and serve WOFF files.
  - Add Source Sans Pro, Source Sans Pro Bold, and the corresponding LICENSE.
  - Add a `font-source-sans-pro` resource for the font.

Test Plan:
  - Changed body `font-face` to `'Source Sans Pro'`.
  - Added `require_celerity_resource('font-source-sans-pro')` in StandardPageView.

Works in Firefox/Chrome/Safari, at least:
