generate_manifest_path()

Public: Generate a new random manifest path.
Manifests are not intended to be accessed publicly, but typically live alongside public assets for convenience. To avoid being served, the filename is prefixed with a “.” which is usually hidden by web servers like Apache. To help in other environments that may not control this, a random hex string is appended to the filename to prevent people from guessing the location. If directory indexes are enabled on the server, all bets are off.
Return String path.
