TcpSocket Tutorial

[Leah Hanson]

I've written a blog post explaining how to use `TcpSocket`s.
It's basically the documentation that I wish we had had when we started writing webstack.jl.

It's here: http://blog.leahhanson.us/using-tcp-sockets-in-julia.html

Excellent tutorial – and really helpful since this functionality is super useful but rather sparsely documented.

This is really nice. We should aim to capture some of this into the julia documentation - both in the manual and in the standard library reference.
