[merge] Typo fix.

Merging with upstream

added default behavior, to allow for unhandled backends, such as 'MacOSX'

Merging Brian's trunk-dev. * Fixed Foolscap import warnings (#525805). * Improved Monte-Carlo options pricing example.

Merging upstream.

Add notes by Brian on Mathematica notebook format.

Add doc about the format for storing interactive sessions. The idea is to use a notebook-like representation, but using plain rst for storage, with a few added directives of our own.

Fixed foolscap imports. As of Foolscap 0.4.3, foolscap introduces a foolscap.api module that all top-level symbols must be imported from. Fixes https://bugs.launchpad.net/ipython/+bug/525805

Improved Monte-Carlo options pricing example.

Work on the development docs. * Added a new inputhook_app.txt to discuss the problems with app creation and the inputhook with matplotlib and enthought folks. * Wrote more on the core design.

Renaming doc to have the .txt extension we are using.

Fix small typo in variable name.

Add design doc about core module.

Fixing two small bugs in :mod:`IPython.kernel`. * In :mod:`IPython.kernel.launcher` we were not handling the lookup of ``job.exe`` properly on Windows if the HPC pack was not installed. * When :mod:`IPython.kernel.client` was imported, Twisted was giving warnings that we have silenced.

Bumping version to 0.11.apha1.

Merging work to get ready for first alpha release of 0.11. This mostly fixes bugs and tests in IPython.kernel.

Fixed bugs in IPython.kernel. * Removed :mod:`IPython.kernel.contexts` and :mod:`IPython.kernel.tests.test_contexts` and all code that used them. This was broken and needed to be removed. Also Enthought has a nice decorator that does this. * Fixed broken tests in :file:`test_multienginefc.py` and :file:`test_taskfc.py`. See https://bugs.launchpad.net/ipython/+bug/505358. * Changed ports number in :mod:`IPython.kernel.tests` to 10111 to avoid conflicts with users who are using the older 10105 ports. See https://bugs.launchpad.net/ipython/+bug/504515. * Fixed logic and bugs in :mod:`IPython.kernel.fcutils` and :mod:`IPython.kernel.clientconnector` related to how FURL files are validated and found. See https://bugs.launchpad.net/ipython/+bug/502790. * Fixed the unhandled :class:`DeadReferenceError`` exception that was happening in :mod:`IPython.kernel.multiengineclient' and :mod:`IPython.kernel.taskclient` when the controller died or restarted. Now we capture that error and raises a :class:`IPython.kernel.error.ConnectionError` that has a better error message. See https://bugs.launchpad.net/ipython/+bug/502796.

Merging from upstream trunk.

Merging Fernando's trunk (fp-trunk-dev) and Brian's edits (fp-review). This is a huge merge of months worth of work by Fernando and Brian. Some highlights: * The test suite has been ported to use the new APIs. * The test suite runs and passes on all platforms!!! * The IPython Sphinx directive has been updated to use the new APIs. * %history works again. * New %tb magic for showing last traceback. * Significant design improvements in the config loaders and applications. * Zillions of bugs fixed. * Completely new %pylab implementation that uses the new GUI support. This allows pylab to be enabled *at runtime*. * Many other things.

Changing revno before merge to trunk.
