This upgrades ContactPicker and PhoneNumberPicker to use the new ContactsContract instead of old Contacts -- Contacts had been deprecated for several OS versions, and stopped working with the newest one.

Also adds PhoneNumber to ContactPicker, as that seems like a useful attribute of a Contact, and PhoneNumberList and EmailAddressList so that users have an option other than using the default.

Tested on Nexus 4 (4.2.2) and Nexus 7 (4.4.2); ran ant tests.
