/*
 * This is a Greasemonkey script for use with ThePirateBay.
 *
 * It adds a new link to the right on the H2-line when browsing
 * or searching, giving you the option to hide rows that has no
 * recorded seeds. Default is to show the seedless rows, and the
 * setting is stored in the GM preference 'showHide'.
 * 
 * This has been tested with Greasemonkey 0.6.4 on Firefox 1.5.0.2
