Copyright Check False Positive

[chipbennett]

Theme Check is incorrectly returning a WARNING on the Copyright check, for a Theme with both a GNU-recommended formatting for Copyright notice and also with "License:" and ":License URI:" tags present in style.css.

Here is an example of the Copyright notice that is returning a false positive:

* Oenology WordPress Theme, Copyright (C) 2010-2016 Chip Bennett
 *
 * This program is free software; you can redistribute it and/or modify
 * it under the terms of the GNU General Public License as published by

 * 
 * Note: see the "Oenology Reference" admin page for copyright and 
 * license information for bundled resources, including fonts and icons

This should return at best INFO, not WARNING, as both "Copyright" and "(C)" - the explicitly searched-for strings - are included. (Understanding that parsing the verbiage could be beyond the ability of the regex here.)

Perhaps a "Copyright:" tag is needed/would resolve the issue?
