[FIX]Added the missing icon and code to display updated trackers in module since_last_visit_new in that fancy jquery mode (how come I didn't know during so many years about that jquery mode?). Updated the icon for new tracker items accordingly to distinguish it from the other. Extra pieces of images taken from openclipart (public domain svg's)
