Feature/polidea team faces

I replaced Chuck Norris with profile pictures of Polidea employees. New coverflow shows all the avatars.
Seems odd to me that we are copying one list into another and in a loop at that (results.clone() could do the work easily. I know we wanted to have final RESULTS, but probably that's not what we really wanted to have. What we have now is RESULTS which is really MUTABLE (clear(), add()) only the container (List) is immutable. This is quite the opposite to what we would like to achieve. In this case we can really easily get an exception when we are getting element and someone else does "clear()". See also my comment about using array instead of list.
