Challenge Button in the Mode Section or Custom Test Option

[LukasOSmith]

Here is what I am proposing. I think having users see an actual challenge button instead of having it hidden in the command line (that most new users don't even know about) will boost user traffic. As shown in the first image

I think the best way to implement this is by w/e the community chooses which button style. I will have them both route to the command line to load the challenge and have the description to pull the message object from the _list.json and to be read kinda like this (I need to work on the style a bit)

I wanna contribute by making the challenges be a lot more motivating for users so I'ma start descriptions (none of the time roles have descriptions so I added some)
