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.
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.

Several improvements to stdout/stderr handling and visual layout of cells.
Now stdout and stderr are kept contiguous (in a single div) if they are being written to continuously, and stderr is shown with a light red background to help distinguish from stdout.
Further, input cells now have a light gray background to help distinguish them from plain stdout areas.
* add think border around input area
* change background instead of foreground on stderr
* only stderr/stdout are output_stream, general text (including streams) is output_text
* reduce vertical padding on stream output, per @fperez
Consecutive messages to stdout or stderr will not be split
into separate divs, until a new message to different stream
arrives.
Appending will only occur when the latest output is the same
as the new one. Interleaving messages will still result in
multiple divs.
* test_for uses import_item, instead of __import__
* test_for now allows a callback, for processing the result of import_item prior to comparison with min_zmq
* callback is only called when min_zmq is defined
* callback's default is to just return mod.__version__
* use this to check tornado version, and zmq as a version tuple
* fix pexpect check to use external.pexpect
These messages are not returned to the browser, but are printed
to the server logs and will help the code readability.
I have also used a more specific code in some cases.
We were having problems with notebook renaming when using uuid5,
as there are many places in the code where we assume that the
notebook id is unique and unchanging as long as the notebook
server runs.
