+Debugger improvements

+The debugger (and ``%debug`` magic) have been improved and can skip or hide frames
 originating from files that are not writable to the user, as these are less

 In addition to the global ``skip_hidden True|False`` command, the debugger has
 gained finer grained control of predicates as to whether to a frame should be
