Support shadow socks

I've updated a lot of to support shadow socks, It's ok now, but It doesn't support http proxy, I will support it in the future.

I release v0.1.0 for a milestone

For two weeks developing, I release a basic version v0.1.0. Both of http(s) and socks have been supported. It's good start. Then I will import shadow socks and users function support in the future.
