/*!
 * Some enhancement on RfD that is enabled by default just for admins
 * Originally was developed inside Merge.js by me but I decided to split it
 * It will add a quick delete button near each header that is requested by merge.js
 * and will add a number near links button so admins can quickly detect an item has
 * not any back link then safely delete it. It also will check recent delete
 * log every 5 seconds and will make deleted item links on RfD red link
 * to prevent conflicts on deletion.
