* It seems that our old setting of visible was causing scroll bars
to appear if font sizes change in Chrome.
* Also changed json -> xml in Download UI.
* I have added page-break-inside logic to div.input and
div.output_area.
* Fixed a bug in CodeCell that was putting the output_area class
on the wrong div.
I had removed a text area focus event earlier today and that
broke the . key. We are still having problems with CodeMirror
elements gaining focus, but this seems to fix the issue.
* 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.
IPDoctest replaces the normal doctest plugin. Previously we did this by
initializing the builtin plugins but skipping the doctest plugin.
However, if the user has a noserc file with 'with-doctest=1' or the
environment variable 'NOSE_WITH_DOCTEST', then nose will try and
initialize the doctest plugin when it isn't there, and barf. This
commit defers the removal of the doctest plugin to the configuration
stage, so doctest can be enabled before it is thrown away by us.
* Previously, when a kernel died due to an external cause, the
notebook/kernel mapping was not removed, so the kernel would
be resused even though it was dead.
* The heartbeat now properly removes the notebook/kernel mapping.
* Both the header and parent_header have a date field that cannot
be json serialized. This field is just removed for now, but
in the future, we will covert the date to a ISO8601 field.
* Better error handling around this code has also been added
to prevent the server from crashing due to malformed messages.
