Add more functionality to the bink stubs to make them behave more like the previous implementation did when built without BINK_SDK_AVAILABLE.

In particular, the intro movie now exits immediately again rather than staying indefinitely.

The important difference is to send the completion callback in plBinkPlayer::NextFrame(), i.e. act as if we had reached the end of the movie.

Storing the filename is to keep plClient::IHandleMovieMsg() from deleting and recreating the plBinkPlayer on every message.

The changed return values are just to better match the previous behavior and probably don’t matter.
