Eliminated use of deprecated Fairmont functions; allow arguments to be passed to ::once handlers; added support for ::serially and ::concurrently EventChannel helpers; added ::sleep EventChannel helper; use getters to lazy-load Mutual subcomponent (ex: EventChannel) -- useful for use in the browser to avoid loading RemoteChannel code.
