Tool/Language/etc

An improvement to the contributors page would be to include each person's avatar, it could be in a grid formation maybe. I haven't looked into if the Github API offers that but I'm guessing it is. Maybe even more info than just avatar could be included, depending on what API offers.

I'm thinking something like they have in this readme.

What do you think @sb2nov?

The API does return a list of avatar URLs as well so I think we'll have the information needed and should be a good change as well.

Looking at the code it would be nice with some template engine if we're gonna have a grid. I'll give this some more thought.
