Unnecessarily complexity in RecyclerView sample

[keyboardsurfer]

I noticed several inaccuracies within your RecyclerView blog post which are reflected in this sample's code.

1. AnimalDetailActivity TransitionName
   Transition names on the views don't have to be the same on both ends of the transition. They have to be unique for their own view hierarchy though and be matched within makeSceneTransitionAnimation. See this for an example.
2. In RecyclerViewActivity: The ActivityOptionsCompat call can be simplified by applying the suggestion of 1.
3. The AnimalItemClickListener's parameter transitionName can be removed when following through with the suggestions so far.
4. You're removing the transition in the ViewPagerFragment on the way back to the RecyclerView.
   There is a better way: When using onActivityReenter you can postpone a transition and remap views.

These suggestions can also be applied within the recycler_view_to_fragment example.

I've adjusted the code to take into account 1, 2 and 3. 4 will take me some more time and I intend to get it done next weekend.
