ZMQStream is the right object to use for event-driven handling of messages, but instead we chose to rewrite half of it in KernelManager.
This removes most of the duplicate code, in favor of using ZMQStream.
also use the pyzmq install() function for using pyzmq with tornado, instead of manually pasting its contents in notebook app.
Most int traits are now Integers
Integer differs from Long only in that small `long`s are cast to `int`, rather than
all `int`s being cast to `long`:
Integer(4L) => 4
Long(4) => 4L

Rebased to avoid recursive merge for just one commit.
This made the notebook server artificially and unnecessarily brittle to tunneling, and non-local hostname resolution. The ws_url is now defined based on the Origin of the request. This allows tunneled hosts and ports to preserve connections, as the ws_url always matches the one in use by the client.
Implemented as a property, to facilitate future cases where it might behave differently.
The notebook now supports a `--read-only` flag, which allows users to view all notebooks being served but not to edit them or execute any code. These actions are not allowed and the buttons, shortcuts, etc. are removed, but the requests will raise authentication errors if they manage to send the events anyway. Save/print functions remain available.
This flag can be used in two modes:
1. When running an unauthenticated server, one can run a *second* read-only server in the same directory on a public IP address. This will let users connect to the read-only view without having to worry about configuring passwords and certificates for the execution server.
2. When running a server configured with authentication (and hopefully an SSL certificate), starting it with `--read-only` allows unauthenticated users read-only access to notebooks. This means that the same server on a single port can be both used by authenticated users for execution and by the public for viewing the available notebooks.
Show invalid config message on TraitErrors during initialization.
implemented via `@catch_config` decorator
Now, the event that was triggered by invalid app config (see `--log-level 5`) is triggered by bad config at any point during initialization.
This *will* catch TraitError-raising bugs in IPython itself, but only during initialization.
Also, deregister crash handler on use to avoid it being triggered recursively/repeatedly.
If a user has Chrome set as their default browser (system-wide or via
the `BROWSER` environment variable), opening the notebook hangs
because the chrome call doesn't return immediately. This solves the
issue by opening the browser in a thread.
Note that there remains an issue where killing the notebook will kill
Chrome if the Chrome session was started by us. I haven't found a way
to work around that despite attempts by making the webbrowser.open()
call in a subprocess.
When using a password, read-only mode allows unauthenticated users
read-only access to notebooks. Editing, execution, etc. are not
allowed in read-only mode, but save/print functions are available.
No kernels are started until an authenticated user opens a notebook.

closes gh-908
This is separate from previous, because it is more likely to be rejected.
It requires the the Session objects in Handlers get a reference all the way back up to the IPython App that started the environment.
* Favicon.ico is served.
* Test suit now passes.
* Help links work for for me.
* Other changes made to address inline comments.
* The printing of long lines is an extremely subtle issue and I will open an issue for it.
* zmqws.py is completely gone so the naked print is not an issue.
* ipython-notebook removed from scripts.
* Updated copyright and authors of files.
* Fixed missing docstrings in IPython.nbformat.
* Full kernel heartbeating is working.
* Connections between the notebook and server and now created
a new each time there is a WebSocket connection. Each channel is
also handled separately. This dramatically simplifies the
server code and makes for a more scalable system.
* ipython_notebook_config.py is now created and staged.
* New certfile/keyfile config=True attributes for enabling SSL/TLS.
* Examples of usage added.
* New handling for --ip=*
* Aliases added.
