Remove Copyright date from all files

[navarr]

Please remove the Copyright date from all files, i.e. this text:

• Copyright © 2015 Magento. All rights reserved.
• See COPYING.txt for license details.
  */

Should have the "Copyright © 2015 Magento" replaced with one of:

• "Copyright © Magento"
• tongue-in-cheek "Copyright © date('Y') Magento"

Why?

One of the most annoying things about Magento 1 is the huge diffs created for the first release of a new year - every. single. file. has changed.

Please don't do that to us again.

Hi, as far as I understand 2015 is not going to be updated ever as it is "the year of the first publication of the work" (see a9e5897).

Otherwise it would be placed in separate file like:
https://github.com/zendframework/zf2/blob/master/LICENSE.txt#L1
https://github.com/symfony/symfony/blob/2.7/LICENSE#L1

If that's true, that's all I want 👍

Unfortunately, somebody came up with 2d368d0. Hope it's the last such massive change.
