v2.0-alpha1

Vanilla groupie is now in module library (com.xwray.groupie) and groupie with databinding is now in module library-databinding (com.xwray.groupie.databinding). They are both available on jcenter.

Items that use data binding should now extend BindableItem.

A fun side effect of this rewrite is that you can mix and match regular Items and BindableItems (maybe in case you want to do a gradual rewrite of an existing RecyclerView?)
