/**
 * This function will Kill 'blogs/editor' rewrite rules
 * to fix the broken pagination issue on this page:
 * '/blogs/editor/'
 *
 * This fix was needed because we add rewrite rules for CPT: editor
 * And because '/blogs/editor/' is also a static page, the pagination
 * on that page e.g., '/blogs/editor/page/4/' was broken. 
 *
 * What I did here is to change priority of rewrite rules served
 * by WordPress so my custom rewrite rule takes precedence over 
 * other rules. 
 * 
 * To get it to work:
 * 
 * $cpt_slug     = CPT slug.
 * $rewrite_slug = rewrite slug of the conflicting CPT and page.
