Add graphical wait_for_light back in

[Zacharyprime]

I created a ASCII lightbulb replacement for wait_for_light.

There is a ~2 second delay added from this which we had to account for at the tournament.

The graphical library now works on Wombat (afaik) so we should add back the old graphical version to prevent an advantage for Wallabies.

This may have been done at the tournament but I'm not sure if it's in master or a seperate branch.

Make sure to take a look at what changes were made on different repositories from July 10th to July 16th.
