cck_field_privacy 6.x-1.0

Initial stable release for the 6.x branch. CCK Field Privacy now uses a hook (hook_cck_field_privacy_access) so that the module does not have to implement code for every user relationship module that is out there. At the time of release, only Friend List implements the hook, however, issues have been filed with User Relationships to add a hook implementation. Thanks to mercobily for bringing up the issue #314170: Plugin architecture for field access permissions + Integration with Friendlist.

Also corrects #220922: Padlock not displayed with custom CCK Types by yoyoman, showing the privacy icon for other CCK Fields (such as Email) that did not display previously.
