- update gradle build config as well

-I also added the public Fabric key to the repo, because it seemed there
was no other way. Really hope no one abuses that.

-And it literally took one line in my Gradle setup, that took 30 seconds
to search for. Last time I tried to fix this it took hours of searching
and I never found a solution. I want to die.

-Only real difference is that RecyclerView items are animated upon
removal
-Also, the color of the favorite button eases in when pressed. No idea
how this happened. I guess it is related to some support library change?
Possibly related to this, the ImageButton can no longer be focused.

- Also made all the stuff more asynchronous. Though it now crashes
when the screen is rotated during the network calls. Oops.

- About page is currently severely lacking in icons
