Fix the copyright statement in source code files to be accurate

[ipython]

Original Launchpad bug 502789: https://bugs.launchpad.net/ipython/+bug/502789
Reported by: ellisonbg (Brian Granger).

The copyright statements in some source files are inaccurate and need to be updated.

What needs to be done for this?
Just copying the 'following banner' from COPYING.txt?

I think so, and would have done that, but I guess everywhere 2010 instead of 2008, isn't it? Or 2008-2010 or whatever?

After an answer, I could take care of adding this everywhere and send a pull-request.

this start to be an old issue.
I don't know the politics of copyright updating:

• all files
• all files already mentionning the Dev Team
• all files already mentionning the Dev Team and edited in 2011 ...

I wrote a small python class the shoul handle simple querry of wether the Copyright is up to date or not and update it if necessary.
I can try to put it in the test suit. As it's not hi-priority i won't make it work also on windows, because it rely on grep and find ...

@Carreau, no need to automate this, it's more likely to break and give build hassles than anything else, and it's not critical. In general, we just have the policy of having a copyright notice at the top of files that says

#-----------------------------------------------------------------------------
#  Copyright (C) 2001-200X OLD Copyrights Always Left intact
#  Copyright (C) 200Y-200Z OLD Copyrights Always Left intact
#  Copyright (C) 2008-This Year  The IPython Development Team
#
#  Distributed under the terms of the BSD License.  The full license is in
#  the file COPYING, distributed as part of this software.
#-----------------------------------------------------------------------------

For new files, it's simply

#-----------------------------------------------------------------------------
#  Copyright (C) 2011  The IPython Development Team
#
#  Distributed under the terms of the BSD License.  The full license is in
#  the file COPYING, distributed as part of this software.
#-----------------------------------------------------------------------------

But it's not the end of the world if one or two files are missing this, and I'd rather never have to debug a grep/find error on BSD vs Linux vs Solaris because of automation here.

A PR that simply updates files that are missing a notice or brings the current year to 2011 where it's not would be fine, for sure.

Thanks a lot, @Carreau. I think the fixes in #1033 are sufficient, closing here.
