func FaviconHandlerFunc(h http.HandlerFunc, path string, maxAge time.Duration) http.HandlerFunc {
	return FaviconHandler(h, path, maxAge)
}
FaviconHandlerFunc is the same as FaviconHandler, it is just a convenience
signature that accepts a func(http.ResponseWriter, *http.Request) instead of
a http.Handler interface. It saves the boilerplate http.HandlerFunc() cast.
