Feature request: Show badges on user selected languages, not on the highlighted 3.

[formidablae]

Let the user decide which badges to show. Displaying only the highlighted 3 badge makes the widget not very informative.

Proposal:

1. Default behaviour = display the highlighted badges.
2. Allow the user to show all the badges.
3. Allow the user to choose arbitrarily which badges to show. This I suppose would need a list of languages as a parameter.
4. Allow the user, if show-all-badges chosen, to hide a list of badges.

I may help to implement this if someone gives me a hand initially to understand how the codebase/project is structured/intended. Thank you.
