/**
 * Automatic updating
 * Updates current plugin automatically (from AlliedModders webpage only, to prevent spreading of malicious code).
 *
 *
 * The file ID has to be the same as it is on the forum webpage. (Check the link of the .amxx file ("Get Plugin" link))
 *
 *
 * If frequency is supplied you can set how often to update the file. If none is provided it will update as soon as possible.
 * Please use this respectfully. Don't overload the AM forums.
 *
 * You can however provide your own method of determining whether the file needs to be updated or not before calling this function.
 * That way you don't stress AM servers when not required. An example of this is in the HTTPX source which uses this method.
 *
 * Examples:
 *    1w = 604800
 *   30d = 2592000
 *
 * I recommend using 30 days or more. How often do you update your code? (Honestly)
 * If the time is set too short and/or is abused, I will remove the function completely.
 *
 *
 * IMPORTANT!
 * The reason for this not being a native is that it does not halt the plugin if HTTPX is not running. HTTPX and automatic updating is optional.
 * Use this example. the File ID is the attachment in your post on the AM forums. Only use the ID, not the whole URL.
 * For example:
 *     The plugin Name Replacer by anakin_cstrike, @http://forums.alliedmods.net/showthread.php?t=77401
 *     Scroll down and hover the "Get Plugin", there you see the file ID. Just replace the placeholder with that value.
 *     #define AUTOUPDATE_FILE_ID "76775"
 *     Add the time or create your own method of deciding when it's supposed to be updated and you're done.

#define AUTOUPDATE_FILE_ID "REPLACE_THIS_WITH_YOUR_FILE_ID"
#define AUTOUPDATE_HOW_OFTEN REPLACE_THIS_WITH_DESIRED_FREQUENCY // 1d = 86400, 1w = 604800, 30d = 2592000 (30d is recommended)

UpdatePlugin() {
    new hHTTPX = is_plugin_loaded("HTTP:X");
    if ( hHTTPX ) {
        new filename[16];
        get_plugin(hHTTPX, filename, charsmax(filename));
        if ( callfunc_begin("AutoupdatePlugin", filename) == 1 ) {
            callfunc_push_int(get_plugin(-1));
            callfunc_push_str(AUTOUPDATE_FILE_ID, false);
            callfunc_push_int(AUTOUPDATE_HOW_OFTEN);
            callfunc_end();

 * Begins download of a URL. Read parameters for information.
 *
 *
 * Parameters:
 *
 *   const URL[]
 *      URL that you want to download.
 *
 *   (Optional) const Filename[]
 *      Where should the information be stored? If no filename is entered it will download as a "stream".
 *      This means the data will be thrown away after it passes the buffer.
 *      You can read the data on progress forward and make use of it there.
 *
 *   (Optional) const CompleteHandler[] = ""
 *      The function you want called when the download is complete.
 *
 *   (Optional) const ProgressHandler[] = ""
 *      The function you want called when the download is in progress.
 *      This will be called every time data is downloaded.
 *
 *   (Optional) Port = 0
 *      The port that should be used.
 *      If this is left at default it will use 80 for http and 443 for https (when supported).
 *
 *   (Optional) RequestType = REQUEST_GET
 *      What type of request should be used.
 *      If this is left at default it will use GET.
 *      Possible values so far are REQUEST_GET and REQUEST_POST.
 *
 *   (Optional) const Username[] = ""
 *   (Optional) const Password[] = ""
 *      These are used to login to sites that require you to.
 *      It's only used for Basic authentication, not POST for example.
 *
 * Returns an DownloadID of the download that may be used to abort the download.
