Add TACHYON_URL Constant to wp-config.php

[kingkool68]

define( 'TACHYON_URL', S3_UPLOADS_BUCKET_URL . '/wp-content/uploads' ); needs to be added to the production server's wp-config.php file after the S3_UPLOADS_BUCKET_URL constant is defined.

Without this constant Tachyon probably won't kick in to action and our URLs won't get written to the CDN version. Things will break. Chaos will ensue etc.
