 * Post entity groups scoped to post types.

 * The post entity used to keep one meta_key index for every post type, so a
 * key shared by several groups (hp_rating in hp_listing_core and
 * hp_vendor_core) was routed to whichever group registered last — a
 * listing's hp_rating landed in the vendor table. Groups can now declare the
 * post types they belong to, and lookups that pass a post type use it.
