Custom status work to date
get_the_title(): When prepending 'Private: ' to a post title, check the post status object for the post's status
_wp_link_page(): Refer to moderation stati, as opposed to 'draft' and 'pending'
get_permalink(): Reflect that other registered moderation stati need to return non-final permalinks too
get_sample_permalink(): All moderation stati should have faked post_names
edit_post(): Use first moderation status instead of 'draft'
touch_time(): Refer to moderation stati instead of hardcoded 'draft','pending'
Publish Meta Box: Defer to 'private' state of post status instead of 'name'
Publish Meta Box: Users without 'publish_posts' can submit to next moderation status

Users without 'publish_posts' now have access to all of the moderation statuses. As such, the "Submit for Review" button needs some amount of flexibility. We allow for this flexibility by referencing a new 'save_next' label, and paying attention to the next moderation status in `_wp_translate_postdata()`
Manage Posts: Always respect the current post type when requesting post stati
