Update copyright/author statements....

Update copyright/author statements. - Updated copyright statements to use the new form: # Copyright (C) 2008-2009 The IPython Development Team I left the old notices in place (just updating the year in some cases), because as far as I know, old copyright statements are not meant to be retroactively modified. - Also, on most files, replaced __author__ marks with an 'Authors' section in the module docstring. This reduces top-level code in the module, while ensuring that the Author(s) get properly acknowledged in auto-generated API docs (sphinx doesn't read __author__ marks, but it will include the module docstring). I only left a few in place for very old files that we ship externally, and for those by Laurent: he had his authorship mark both in the docstring and in __author__ variables, so I think out of courtesy it would be better to ask him about it on the list. All the others were I found regular __author__ variables, I moved them to the main docstring.

      WARNING: this script exits IPython!  It MUST be run in a subprocess.

      When you run the following script from CPython it prints:

      __init__ is here

      __del__ is here

      and creates the __del__.txt file

      When you run it from IPython it prints:

      __init__ is here

      When you exit() or Exit from IPython neothing is printed and no file is created

      (the file thing is to make sure __del__ is really never called and not that

      just the output is eaten).

      Note that if you call %reset in IPython then everything is Ok.

      IPython should do the equivalent of %reset and release all the references it

      holds before exit. This behavior is important when working with binding objects

      that rely on __del__. If the current behavior has some use case then I suggest

      to add a configuration option to IPython to control it.
