Migrate contact xref to liberty_xref tables; add address_postcode to schema

5.0.1 upgrade migrates contact_xref_type/source/xref data into
liberty_xref_group/item/xref with content_type_guid='contact'.
5.0.2 upgrade drops the old contact_xref* tables.

schema_inc.php updated for fresh installs:
- Removes contact_xref, contact_xref_source, contact_xref_type tables
- Adds address_postcode table (UK postcode lookup, LEFT JOIN'd in queries)
- Defaults now INSERT into liberty_xref_group and liberty_xref_item directly
- dependencies => 'liberty' ensures correct install ordering

PHP and templates: source→item, xref_type→group rename throughout.
