Client wants to show stars rating on smartbanner

[wcc-crystal]

My client is wanting to see how it looks with stars, and I was wondering if anyone else has tried to add that to the smartbanner. I am going to attempt to try, but I do not know exactly where to start yet as I just installed smartbanner this hour.

The stars were discussed in #50 and the support will come, but the work has not yet been started. Contributions are therefore more than welcome!
