Fixed a bug (#2) that caused attachment download to fail. Many thanks to @alexbers.

v0.2 — epoll and kqueue, lower pings

Added support for epoll (Linux) and kqueue (MacOS/BSD) network transports, which further improve network performance.

v0.1 - first release

Initial release. Implemented features:

• Fully asynchronous and non-blocking: 4 threads to handle a lot of connections;
• Built-in support for HTTP passthrough: some public Wi-Fi networks block connections to a non-standard ports, so run your proxy on 80 port without having to sacrifice your web server;
• Proxy through proxy: this is feature is mainly useful at development, since I cannot reach Telegram servers directly in Russia;
• Collection of a traffic statistics.
