Storing base64 encoded fonts in localStorage. Prevents FOIT on initial visit, and FOUT on subsequent visits.

	// Load fonts
	//
	// The technique is a combination of using fontfaceobserver and storing data-uri
	// encoded fonts in the localstorage for perfect font loading experience.
	//
	// FontFaceObserver eliminates any visible flicker (FOIT) during the initial load,
	// by simply swtiching from fallback to primary typeface when fonts are loaded.
	// Permanently caching fonts as a CSS file in localstorage completely eliminates FOUT on subsequent visits.
