- refactored and fixed listing issues (related to Segments)
- removed bulk actions from segments
- added synchronize methods for WP users
- Update action in segments only for WP Users list
- added "type" column to segments (default, wp_users, dynamic...)
- added "status" column to subscriber_segment table (useful soon)
