Add per-page filter for nav menu post type meta box

[wpsmith]

Currently, there is a default (50) for paginating Post Type Entries on the wp_nav_menu_item_post_type_meta_box(). While there are other ways to filter this, it would be great for larger sites or larger number of post objects to be able to increase this for UX reasons.

Seems reasonable to me, though I'd propose a filter named wp_nav_menu_per_page instead.

+1. Would love to see this as well. Another use case is wanting to also include private pages (and other post types) in the post type meta boxes. We have several clients who like to set pages to private while developing, which means these pages won't appear in the "Most Recent" or "View All" tabs in the post type metaboxes on the menus admin page. It would be great to be able to filter the $args passed to the $posts = $get_posts->query( $args ) call.

I agree that the filter should be renamed to something more obvious, maybe even something like wp_nav_menu_posts_per_page, or mimicking the list table *per_page hook, wp_nav_menu_{$post_type}_per_page.

At the very least, the patch will need a refresh and regeneration from the root directory. The filter will also need ​hook docs.

wp_nav_menu_item_taxonomy_meta_box()​ should get a similar filter for consistency.
