Feature/polidea team faces

I replaced Chuck Norris with profile pictures of Polidea employees. New coverflow shows all the avatars.
I think we should use Result [] here rather than list. The usage pattern is that we never actually add anything to the list. We have "setResources" with list of results and there effectively we replace the whole "list" (clear(), for() { add} ).  What we really wanted to achieve here (capital RESULTS suggest that) is that the RESULTS is immutable. We cannot fully achieve that (We cannot have immutable array in java, final does not make it immutable). Alternatively we could use guava's ImmutableList or Collections.unmodifiableList() - if we really wanted a "constant" - i.e. immutable results  here.
