/* benski: basic thoughts
ExternalObject will be created "on demand" when ml_online loads a page
so ExternalObjects will have a lifetime (unlike ExternalCOM which is a singleton)
create wasabi services for creating window.external.* objects
when a window.external.* function is requested, services are enumerated
the key is passed to the object creator. The returned object will be treated
as a singleton from ExternalObject's perspective. It will be Release()'d when
the ExternalObject is destroyed.
the basic layout will be
window.external.API.method
e.g.
window.external.Transport.Play();
any time that non-singleton objects need to be created (Config object,
playlist object, etc) they will be created from a method within the API object
e.g.
var new_playlist = window.external.Playlist.Create();
