This function downloads a file from the HTTP server. This can only be used on files on the HTTP server associated with the MTA server and will only download files from within the folder of the resource that is calling it. The file should also be included in meta.xml with the download attribute set to "false", see meta.xml for more details. If the file has been previously downloaded and the CRC matches, the file will not be downloaded again but onClientFileDownloadComplete will still run.
