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.
