LPS-37506 - Theme thubnails are screenshots of the old ones

Hey @ronaldf10,

Attached is an update for http://issues.liferay.com/browse/LPS-37506.

We need to update the screenshots again to match what was in the original images.  The original images had multiple pages in the navigation, the "Sign In" portlet, "Language" portlet, and "Web Content".  I am getting you a high resolution PNG of the Liferay logo image to use for the "Web Content" portlet.  Also, the Control Panel site is "Zoe Test" when it should be "Liferay".

Please let me know if you have any questions.  Thanks!
