Now you have to pass all items and 3 optional params have been added.
- CoreCourseModulePrefetchDelegate.getPrefetchHandlerFor now admits module name instead of full module object.
- CoreCourse.getModuleBasicInfoByInstance and CoreCourse.getModuleBasicInfo have been modified to accept an "options" parameter instead of only siteId.
- The function CoreFilepool.isFileDownloadingByUrl now returns Promise<boolean> instead of relying on resolve/reject.
