incorporated reporter

@kpiwko @okiss 

it does reports by default, screenshots with -Pscreenshots

I was looking at the code to treat that screenshooter programmatically but it is wired pretty much deeply.... 

If we want to merge it, I would wait for 0.2.10 of parent where is graphene 2.1.0.Alpha1 (as PR) and I am about to release 1.0.0.Beta1 of reporter as well so bumping would be neccessary anyway in the near future.
