Completed TLGCIC-43 parts 1 & 2 with changes:
 a - JSON object "googleLinksConfig" is created by GoogleLinksServiceAccountManager as Velocity variable $portalLinksConfig
 * Done in Java: Velocity would need to parse $portalLinks as it contained runtime data values
 b - $portalLinks set to load script googleLinks.js in /library/htmlarea
 c - "M+ Google" DOM is inserted onto the page using $(<parent>).prepend('<menu-dom-tree>');
