API modifications to handle profiles in Contacts.

The user's profile is represented as a single Contact, comprised of
Raw Contacts which may be contributed from any accounts the user has on the
system.

Two new permissions have been added: READ_PROFILE and WRITE_PROFILE.  These are
required for reading or writing any contact data that is designated as part of
the user's profile.

Contact queries can include the user's profile data by setting the
include_profile URI parameter to 1 (this requires READ_PROFILE access).  By
default, the user's profile data will not be included in any Contact queries.
