add websocket port forward for Vagrant

Forward the websocket port out of the virtual machine so the browser can connect to it

@AlanHohn @popey456963 nice work on the Vagrant setup! How's it going now–still any known issues, or pretty solid?

@AlanHohn gets all the credit, I've changed a whole word of code.

In terms of progress, vagrant might be getting to the stage where we can release it to the public. This pull request in particular, makes it a lot easier to use, allowing the client to get to the website. I'm not sure which OS Alan is using, but on Windows it works well.

The user will only need to install vagrant + an ssh client of their choice. Then it should be as simple as vagrant up.

Note that they'll only need an ssh client if they wish to access the box once it is up.

I'm mostly using a Mac, but did some testing on Windows as well. I installed Git for Windows and got SSH that way.

I am running into one issue, at least on Mac, which is that brunch doesn't appear to pick up my changes if I make them on the host. If I SSH into the VM and make a change it gets picked up right away.

So it's not quite at the point where it's easier for a novice user, but it's close. Certainly it's easier for me as someone who knows more about VMs and Linux than about Node.

Ah, we definitely need to make a note of that - I reckon most (at least some) will have only installed Git_hub_ for windows, which does not include SSH.
