There is a suspected problem with the way the id handler of the manifest parser is managing odd characters

This problem has manifest itself in a couple of ways. There has been strange behaviour when uploading some of the w3c test widgets directly to the server rather than through the test rig. With the server running unix type systems the widget will not run correctly but on windows the widget will not load.
The suspicion here is that the id handler is attempting to create folder names with path separators in them or other illegal characters.
The other evidence pointing towards this issue is the update behaviour again on windows not working correctly. When the same widget is dropped into the hot deploy folder twice the second time wookie should update the widget, on windows, however, another installation of the widget is occuring.
