Copy name from scoreboard feature added to challenge login -- good for Team Challenges :)

We've added a new feature allowing users to select from names that are already on the scoreboard when they log in to a challenge.

Why? 

Well, this makes logging in much easier for Team Challenges, where you want several students to use the same scoreboard name to identify their team. (Previously the log-in box appeared in front of the scoreboard, so it wasn't easy to copy existing names...)

That's all. Just a little tweak to make things smoother. 

(A number of people had asked for this feature...)
