New Apache source file header...

[Chad Schoettger <ch...@gmail.com>]

If developing with an IDE that supports file templates (such as
Intellij IDEA, Eclipse, etc) it will be necessary to update the Apache
source file header (if it is included in your templates) to the new
header which can be found below or at
http://www.apache.org/legal/src-headers.html

  - Thanks, Chad
