Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account. This has the side effect that function break points are not converted into script break points for named scripts. Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.
