Add carousel

[paususe]

Six featured projects, featured statically, seems a bit short. What about adding a carousel to be able to display more featured projects?

Please note I am not saying all projects should be featured but that the subset of featured projects is probably going to be more than 6.

I. e.
Total suse-projects = N
Total featured projects = M (where N > M)
Total displayed featured projects = 6 (where M > 6, hence there's a case for a carousel)
