Try and improve the print-backtrace-and-exception/knots output, be selective about the stack frames which are shown to try and produce some useful output which reflects user code and hide the &knots-exceptions. This commit also introduces a bunch of tests scripts that produce output from print-backtrace-and-exception/knots, to help test this code in different situations.
