The About page has a `<div>` that doesn't close. Also, `<hr>`s should self-close. `hackificator` complains about these things.

See #27881.

Because the `WP_ADMIN` constant name can be bound in multiple files, all instances should check `! defined` first. `wp-admin/admin.php` already has this check. 

See #27881.

`hackificator` complains if you call `include 'file.php'` without the parens, needs to be `include( 'file.php' )`

See #27881.

See #27881.

In `edit-link-form.php`, `hackificator` bails because there is a `</form>` with no open `<form>`. It exists, but is needlessly constructed with PHP. It always returns a `<form>`, only the `id` and `name` are different. The dynamic piece just returns the ID now.

See #27881.
