Triggering Wired Actions When an Embedded Movie is Loaded

A new MovieLoaded QuickTime event has been added that allows wired actions to be executed when an embedded movie is loaded. There are two places to store these actions. The movie that is being loaded may store actions in its movie properties atom container, and the movie track may store these actions in its samples.

These wired actions can be used to examine the current state of the parent movie, and to make changes both to the movie being loaded and to elements of the parent movie.
