16714	Introduce capabilities for adding new posts	nacin	casben79	"Many plugins need to be able to deny the creation of new items, particularly for CPT use cases. Unfortunately this is not easy to do.

I am suggesting a new cap for adding posts. Obviously, this has the potential to break quite a number of custom roles, but I think we can avoid that.

Instead, it would by default simply map to edit_posts. It wouldn't actually get assigned to any roles, so it's more or less a meta cap. (Only, without an $id, because it'd be a new post even pre-auto-draft in some cases.) But it then opens up the ability for this to be filtered by a plugin.

We could also potentially add this to the CPT capabilities array, but with the default being 'add_posts' => 'edit_posts'. Ultimately there are a few ways to implement this.

Ideally, the cap should be used for the admin menu, for post-new.php, for the 'Add New' button (no more clunky hiding it via CSS), XML-RPC, and the post handler for post-new."	task (blessed)	closed	normal	3.5	Role/Capability		normal	fixed	needs-docs has-patch commit	frank@… kevin@… johnbillion@… marko@… pauldewouters
