Half NetCat

Partial netcat compatibility was achieved and a major refactoring (almost rewriting) of the project was done.

After I finish some more features, I'll document how people can extend this thing (also thinking about python, aside from go).

Also windows! 🎉

Initial Release!

Currently due to the ugly hack that I pull to fix mattn/go-tty#24, there are no windows builds. Also I can't test windows stuff (I can't even get a revshell), due to technical problems, that I hope I'll solve sometime soon.

Happy Hacking!
