New hooks when taxonomies and post_types are registered

[simonwheatley]

These new hooks allow plugin and theme developers to react to post types and taxonomies being registered.

I've created the diffs with Git, and they look different to the SVN generated ones I'm used to, so let me know if they aren't acceptable.

New hook registered_post_type for register_post_type

New hook registered_taxonomy for register_taxonomy

+1 for this. Now the only way to register something for each post type (e.g. add custom column to post list) is to register hook for init action with high priority value, to make sure all custom post types and taxonomies are already registered.

These sound like a great idea.

I'm half convinced to call this a bug not an enhancement ;)

Fire an action when a post type or taxonomy is registered so plugins can react. Fixes #18802 props simonwheatley.
