Allow for register_post_type() to enable/disable revisioning of new post_Types

[dd32]

At present, Only pages and posts are allowed to be revisioned, It'd be good to leverage the revisioning system for custom post types.

I personally think that it should be disabled by default for post types, and enabled specifically.

I'll submit a patch to this effect at some point.

• Only changes the backend, Doesnt touch the front end implications.
• Need to verify if any front end functionalities need to be modified to allow it
  • Pretty sure that the meta boxes will need updating once the Post Type UI goes in

This depends on the talk for Post_type_supports() chat over in #9674 as well.

Patch is now stale, Will update it when the above is sorted out..

Implements revisions for all post types that specifically support 'revisions'

Implements passing an array (or string) 'supports' in the args of register_post_type to allow for register-time registering of what features the post type supports.

Could do with a singular/plural form of the post type..

Leaving here for review by anyone who's interested.

(In [12751]) Introduce Revisioning for custom Post Types, Introduce 'supports' argument to register_post_type() to wrap add_post_type_support(), Whitespace additions to create_initial_post_types(). See #9674. Fixes #11703
