ZVISION: Make video code blocking.

The script system requires that all ResultAction::execute() block until they finish. The video system *was* 'asyncronous'
in that you would just start a video and then run() would finish processing it. This code forces the video to complely finish
before playVideo returns. The Clock object is used to keep track of deltaTime while the video is playing.
