 *
 * AutoImportationStatus is 1 if the script should be auto imported when the
 * console opens.
 *
 * FetchedStatus has two purposes:
 * - It is used to detect which scripts are imported in the console, so we can
 *   retrieve the correct variables afterwards in the variable box. When a
 *   script has been imported, its fetchedStatus value is
 *   FetchedStatus::FromConsole.
 * - It is used to prevent circular importation problems, such as scriptA
 *   importing scriptB, which imports scriptA. Once we get the variables from a
 *   script to put them in the variable box, we switch the status to
 *   FetchedStatus::ForVariableBox and won't reload it afterwards. */
