Update codemirror to 2.15 and make the code internally more version-agnostic.
Added our own README file with information about what changes we carry to upstream CodeMirror and what version we currently use.
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
Simply call it 'codemirror', so we don't have explicit version numbers
inside a bunch of files.
A file called ipython-version-N.NN will be kept to easily let us know
which version we're shipping with IPython.
* 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.
* 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.
