Allow capability_type to be an array, for odd plural situations such as story/storys/stories. After registration it reverts to a singular string. Lots of documentation for meta capabilities and post types, also some cleanups for register_post_type documentation. see #14122.

* - read_post - The meta capability that controls reading a particular object of this post type. Defaults to "read_ . $capability_type" (read_post).
* - read_private_posts - The capability that controls reading private posts. Defaults to "read_private . $capability_type . s" (read_private_posts).
* - delete_post - The meta capability that controls deleting a particular object of this post type. Defaults to "delete_ . $capability_type" (delete_post).
* Post type capabilities use the 'capability_type' argument as a base, if the
* capability is not set in the 'capabilities' argument array or if the
* 'capabilities' argument is not supplied.
*
* The capability_type argument can optionally be registered as an array, with
* the first value being singular and the second plural, e.g. array('story, 'stories')
* Otherwise, an 's' will be added to the value for the plural form. After
* registration, capability_type will always be a string of the singular value.
*
* By default, seven keys are accepted as part of the capabilities array:
*
* - edit_post, read_post, and delete_post are meta capabilities, which are then
* generally mapped to corresponding primitive capabilities depending on the
* context, which would be the post being edited/read/deleted and the user or
* role being checked. Thus these capabilities would generally not be granted
* directly to users or roles.
*
* - edit_posts - Controls whether objects of this post type can be edited.
* - edit_others_posts - Controls whether objects of this type owned by other users
* can be edited. If the post type does not support an author, then this will
* behave like edit_posts.
* - publish_posts - Controls publishing objects of this post type.
* - read_private_posts - Controls whether private objects can be read.
* These four primitive capabilities are checked in core in various locations.
* There are also seven other primitive capabilities which are not referenced
* directly in core, except in map_meta_cap(), which takes the three aforementioned
* meta capabilities and translates them into one or more primitive capabilities
* that must then be checked against the user or role, depending on the context.
*
* - read - Controls whether objects of this post type can be read.
* - delete_posts - Controls whether objects of this post type can be deleted.
* - delete_private_posts - Controls whether private objects can be deleted.
* - delete_published_posts - Controls whether published objects can be deleted.
* - delete_others_posts - Controls whether objects owned by other users can be
* can be deleted. If the post type does not support an author, then this will
* behave like delete_posts.
* - edit_private_posts - Controls whether private objects can be edited.
* - edit_published_posts - Controls whether published objects can be deleted.
