No longer requires a specific image handler. File system operations now using XenForo file functions.
Now supports running from the terminal.
Fixed issue with undefined variable in previous version.
Using XF HTTP client for requests. Now bypasses animated GIF's with over 100 frames.
Removed functions which were seldom used in order to make the add-on easier to use.
Added PHP directive default_socket_timeout to ensure dead hot links timeout in a short time.
