Changes on badges visualization

Hi!

I did some changes on the way badges are visualized:
* Ability to show/hide badges title.
* Ability to show/hide badges description.
* Badges are a list.
* Several badges can be displayed on the same line.
* Badge css can be personalized.

I put a couple examples in the attached image:
