Display project languages

[karan]

I had to click through the project page, and then come to Github to see what languages a project is written in. It would be great of this information was displayed right next to the project.

PS: I know this is the month of python, but there is a mix of languages in projects. It's useful to show all of them.

We recently added code to check this. But it wasn't quite ready to go. I'll be working on it this soon.

Awesome! :)
