Fixed some copyright and license statements in the file header DocBlocks

These lines were found by using some Regex:

Valid:
`` * Copyright (c) Cake Software Foundation, Inc. (http://cakefoundation.org)``
Regex:
``\* Copyright (?!\(c\) Cake Software Foundation, Inc\. \(http://cakefoundation\.org\))``

Valid:
`` * Licensed under The MIT License``
Regex:
``Licensed under (?!The MIT License)``

Valid:
`` * @copyright     Copyright (c) Cake Software Foundation, Inc. (http://cakefoundation.org)``
Regex:
``@copyright\s*\w(?!opyright \(c\) Cake Software Foundation, Inc\. \(http://cakefoundation\.org\))``

Valid:
`` * @license       http://www.opensource.org/licenses/mit-license.php MIT License``
Regex:
``@license\s*\w(?!ttp://www.opensource.org/licenses/mit-license.php MIT License)``

Those regex could be incorporated into the Jenkins Server for example...
