Allow filtering what is a 'non-deleted' post in transition_post_status hook

[medfreeman]

Hi,
thanks for your work!

I've recently got a contract where i'll have a huge need of this plugin.
So i'll submit a bunch of feature requests / improvements in the next few days / weeks, and provide accompanying pull requests.

My use case is:

• I'm making a simple restricted content plugin where some posts (or any singular post type object) have to be private, but accessible via a specific url containing a key triggering a transparent login to a restricted account (having only read_posts and read_private_posts capabilities)

• After a lot of research i determined that the best way to do this is to use the 'private' Wordpress visibility option, to avoid a lot of coding regarding the content not being available in SEO, posts lists, etc...

• These 'private' posts have to be shareable via json API to a third-party, that will publish the private links in a member area

So the goal is to add a filter on this line.

A good name could be 'jras_listener_post_statuses' ?

That filter name works. Thanks!
