 *
 *  Dynamically load scripts and script queues (when load order is important)
 *
 **********NOTE********
 *  If you need to load any scripts before ScriptQueue exists, use the following snippet
 *  <code>
 *      if (!(window.ScriptQueueIncludes instanceof Array)) window.ScriptQueueIncludes = []
 *      window.ScriptQueueIncludes = window.ScriptQueueIncludes.concat(scriptsarray);
 *  </code>
 *  ScriptQueue loads all the scripts, queued before its' load in the ScriptQueueIncludes
