Organization field expands when tapped

- In order to show as many fields as possible on the
contact editor, we collapse the editor into a button
that only expands the EditText fields when tapped
(collapsing is not possible unless the user exits
the editor).
- Add an isEmpty() method on the KindSectionView
so we can distinguish between a contact with existing
organization info versus a contact who has an empty
organization field
