Revamped Test Module

The new RootTestViewController has now a UIPagerViewController in one region of the screen. Buttons and progress view are now static. The old fullscreen TestCardsStackViewControler is gone. Now it's possible to modify any aspect or behavior (for example add a page counter should be trivial now)

Also, the new TestCardView has a more physical presence (a card over the application background) and has a nice two steeps animation to shows the results. The current card background is a crude hack from buttonHome
