// addToFav script
// Author: Alec Hill
/////////////////////////////////////////////////////////////////////////

// DESCRIPTION
	//this script will open the add bookmark dialogue of your browser and automatically fill in the url and the title 
	//you will need a link with id="addtofav" which will be the link to click, use href="#" so that it is valid, and do not add any text to click, as this script will add that at runtime, so if the script will not add a favourite on a particular browser, it will not display a link, degrading gracefully
