[Plugin: Search Everything] Breaks admin search function for internal linking

I was able to get search/SE working for internal links on the admin page/link dialog popup.

The issue is that $wp_query->query_vars['s'] is not set by that form, it uses $_POST['search'] instead.

In search-everything.php, everywhere there is a if (!empty($wp_query->query_vars['s'])), I added if($_POST['search']) {$wp_query->query_vars['s'] = $_POST['search']; } on the line before.
The only exception to the method is the conditional statement at 153, which is a shorthand method.

Then, and though it pains me, I hacked the core /includes/class-wp-editor.php. On line 695, I changed the suppress_filters value to ‘FALSE’.

I know this probably isn’t ideal, but I really needed to get this working for a client. The obvious drawback is that a WP update will likely break this again.
