//Causes a Shockwave object to play, stop, rewind, or go to a frame.
//Accepts the following arguments:
//  objStr   - name of shockwave object (full objRefs ok too)
//  x        - not used (here for backward compatibility)
//  cmdName  - method to invoke: Play(), Rewind(), GotoFrame(frameNum),
//             StopPlay() for a Flash Movie, Stop() for Director
//  frameNum - (optional) frame number, only used with GotoFrame method
//
//Tries to find the object, which only succeeds if the plugin is there.
//Evals the concatenated pieces to call the method, for ex: document.myShock.Play()
