Script Summary: Allows you to modify Links
originally from http://userscripts.org/scripts/show/27909
changed to be able to change part of a link target , like
www.facebook.com/detail.php?id=123456
(this is the person's actual address)
www.facebook.com/addfriend.php?id=123456
(this is the link that can direct add friend on page)
to do this here is the command you should use
modifyLink_Target ("","www.facebook.com/detail.php?","","www.facebook.com/addfriend.php?",1);
