added transports to gunicorn worker and nginx worker without websocket support
allow transport to be overridden
Add information about nginx

Few caveats with this commit:

1. I'm not sure if `.. code-block:: nginx` makes sense, but the preview pane here seemed to accept it (I'm making this commit via the github interface)

2. I said the client will always fallback to long-polling when it fails to make a connection via websockets. I'm not sure if it always will fallback to that, but in my testing (i.e. on *my machine*) that's what happened. For all I know it might decide to fallback to flash instead. I really don't know how the client side of socket.io works.
Fixed graceful shutdown when running GeventSocketIOWorker with gunicorn.

The old behavior always causes graceful_timeout to elapse instead
of allowing free workers to terminate immediately.
updates socket.io.js used for testing to 0.9.11
using socket.io.js 0.9.16 for tests
handling XHR disconnect. #63
correctly returning 200 OK when disconnecting. #63.
Mention event handler magic earlier in docs

There may be a better way to phrase this, but the docstring left me wondering how  one was supposed to bind a method to an event.
