Global variables:
  isXT: XT builder or not. This variable is set by builder node server.
  isBuilder: is builder or app. This flag is used to distinguish the build and app in jimu.js
  isRunInPortal: whether the app/builder is in portal or not.
  builderNls: the builder nls bundle
  portalUrl: the portal url
  configWindow: in builder only, the config app window object
  previewWindow: in builder only, the preview app window object
  setConfigViewerTopic: in builder only, used to communicate between builder and config window
  setPreviewViewerTopic: in builder only, used to communicate between builder and preview window
  appId: in builder only, the current opened app id.

  apiUrl: the URL of the ArcGIS API for JavaScript
  allCookies: all cookies
  path: the builder/app path section in window.location
  appPath: the app's path. In app, it's the same with path; In builder, it's not.
  queryObject: the query parameters
  jimuNls: the jimu nls bundle
  isRTL: the language is right to left,
  wabVersion: the wab version, like 1.1, 1.2
  productVersion: the product version, like portal10.3, online3.5, developer edition1.0

  dojoConfig: the dojo config object
  jimuConfig: defined in jimu/main

  weinreUrl: for mobile debug
  debug: boolean. If it's debug mode, the app will load weinre file

Global functions:
  loadResource: load JS or CSS
  loadResources: load array of JS or CSS
  testLoad: load JS/CSS by condition
  loadingCallback: the resources loaded callback
