// @description   Adds links to subscribe to site feeds via Netvibes
//			Based on the subscribe to bloglines script by Johan Sundstrom http://ecmanaut.blogspot.com/2005/11/subscribe-to-feed-user-scripts.html
//			I have simply modified the url and replaced the inline bloglines logo, with a link to the netvibes one.
