Thargoidifier OXP

  To add the test functions "Thargoidify System" and "Reset Thargoidification" to
  the F4 screen, in any world script, in the startUp or startUpComplete functions, set:

    worldScripts.Thargoidifier._testing = true;

  In pre-1.0 versions of this add-on, this will be set to true by default;
  to hide the testing functions, set: 

    worldScripts.Thargoidifier._testing = false;

  This cannot be changed after startUpComplete.
