Handle saving and communicating selected tab between View/Edit activities.

EditContactActivity now accepts intents with raw_contacts instead of
contacts. In addition it reports back which raw_contact was selected on
exit.

ViewContactActivity now saves and restores which raw_contact was
currently being viewed, and uses the raw_contact reported back from
EditContactActivity. The overall effect is when moving from View->Edit
or Edit->View the selected tab doesn't change.
