generally not necessary, but sometimes the kernel connection can be dirty.
We have only seen this by starting a qtconsole via %qtconsole,
then killing the kernel, at which point the original notebook's connection
(at the zmq level) is never restored to the new kernel at the same endpoint.
It's weird, and probably a zmq bug, but a simple reconnect seems to solve it.
Introduce Notification Area
This allow several notification widget to be next one to the other in the notification area.
The Api allow also to register a callback if the user click on the notification. and allows sticky and non sticky notification.
* Kernel doesn't depend on Notebook or CodeCell.
* CodeCell doesn't depend on Notebook, only Kernel.
* All of the kernel management logic has been moved out of the
Notebook into the Kernel.
* Public methods of the Kernel (execute, complete, etc) take
a callbacks object that registers the callbacks for that msg.

1. Users are warned when an older nbformat notebook is converted.
2. The notebook notifies the user when a notebook that is too new
is attempted to load.
To test these things, create a simple notebook. Then change its
nbformat field by hand to 2 (to test 1) and then 4 (to test 2).
* Refactored the save widget so that the notebook doesn't depend
on it. Now the notebook emits events and the save widget
observes those events.
* Created a new event system for all IPython events (events.js).
We should start to use this to allow our classes to be loosely
coupled.
* Created a new notification widget that should be used for all
notifications. Uses new event system.
* Removed the kernel status widget.
* All kernel status message use new event/notification system.
* The print notebook view works again.
When user press '(' and nothing for 1200ms, 'object_info_request' sent to
the kernel. Then tooltip with 'definition' and beggining of 'docstring'
shown to the user if non empty response.
Unlike Completion <select> , <div> is not focusable so event handled in main
cell event handeling function
Add some CSS3 that most browser with websocket should support.
A long message is given if the connection fails within 1s. Otherwise, it is a short 'connection closed unexpectedly'.
This also means that clients are notified on server termination.
stdin requests are now directed to the frontend that made the execution
request that called raw_input.
allow_stdin flag added to execution_request to indicate whether stdin_requests are allowed.
StdInNotImplementedError exception class added to IPython.core.error, and is raised if raw_input is called from execute requests where allow_input is undefined.
closes gh-673
* 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.
