- Revision ID: edam@waxworlds.org-20110502182824-acgdi3qfxfzqgely
- fixed logic for vcard field types (home, work, cell, etc) so it works
- updated NEWS and TODO
- rewrote most of ContactsCache, including a new ContactIdentifier class to identify contacts in the cache and new cache building code
- contacts now identified in the same way that Andoid displays them (by name, or organisation, or number, or email, in that order)
- propper handling and support for organisations and titles
- validation of imported contact now done by Importer, not VcfImporter
- separated sanitisation and normalisation (for cache lookups)
- generacised PhoneData, EmailData and AddressData classes
- ContactData is now aware of primary numbers, emails and organisations (defaults to the first prefrred one seen, or the first one seen where none is preferred)
