Postal Code Suffix (Zip+4) - Expose in Contact Export, Import, and Profile

Postal Code Suffix property of the Address object is currently only expliictly available in the Edit Contact form. We need to expose it in Contact Export, Import, and Profile:

Export:

• Output a separate column for "Postal Code Suffix" in the default (Primary Contact Data) export data set.
• Add Postal Code Suffix to the select option list for 'Selected fields" export.

Import:

• Add Postal Code Suffix to the select option list for 'Matching CiviCRM Fields'.
• We should retain the existing code which attemps to populate postal_code_suffix automatically from the postal_code import data. It looks for a dash delimited list and parses it into postal_code and postal_code_suffix fields. We will 'ignore' the edge case where the user has mapped postal_code_suffix AND has nnnnn-nnnn data in the postal_code field (the code can just use whichever data comes last in this case).

Profile:

• Add' Postal Code Suffix' to the select option list for 'CiviCRM Field Name' - and verify that create, search, listings and view (details) functionality works with this field. (Since this is an Address property, it will always have an associated location_type, same as Postal Code.)
