Add a delay start time to config file to allow a hdmi monitor/tv to connect before playing animation.

Problem:
Currently the animation is halfway through playing before an hdmi connected monitor does its digital handshake and presents a picture.

Suggestion:
Add a adjustable variable to the cubeboot config file that would allow the user to set a "xx" second delay. This delay would allow the gamecube to first fully initialize with a hdmi connected monitor or tv before starting the animation.
