Expand MetaBoxReset to include column visibility and view count

[joemaller]

• View count uses usermeta keys like: edit_{$post_type}_per_page
• Column visibility uses usermeta keys like: manageedit-{$post_type}columnshidden
• Media Library column visibility uses this key: manageuploadcolumnshidden
• Media Library per_page uses this key: upload_per_page

In the above examples, $post_type is the post_type slug.
