Merge branch 'cleanup-old-code' of http://github.com/takowl/ipython into takowl-cleanup-old-code Various cleanups of old and deprecated modules, this helps keep the code tidier for the py3k branch and future migration. Closes gh-180 (pull request).

Merge branch 'minrk-pygments' into trunk Provide full support for all the Pygments styles at the console, and properly synchronize with IPython's own Linux/LightBG color schemes. In the long run we need to refactor our internal coloring code to only use CSS, but for now this provides a fairly clean user experience. Closes gh-171 (pull request)

Merge branch 'fix-del-method-exit-test' of http://github.com/takowl/ipython into takowl-fix-del-method-exit-test Fix errors with __del__ methods being called on exit. This branch reintroduces a recent fix that got accidentally overwritten, as well as adding a more stringent form of the test so that we don't miss it again in the future (the old test only printed a message but didn't fail, so it was easy to miss). Closes gh-172 (pull request).

Merge remote branch 'minrk/htmlfix' into trunk. This branch implements a number of improvements to the HTML save capabilities of the Qt console, and received extensive reviews. A short summary follows, see the pull request page for full details, at http://github.com/ipython/ipython/pull/170. Some small issues in the HTML code I noticed when I started playing with it. * only rich backends support toHtml, so the html/xhtml exports failed * modules were imported inside functions * relpath in image_tag was determined in platform-dependent way * save dialog strictly enforced non-standard '.htm' file extension * when selecting external PNG, the _files dir was always created, regardless of whether there were any images Fixes in this commit: * export options do not appear in non-rich widgets * module imports all at the top * relpath uses platform independent os.path * dialog uses standard '.html' by default, but allows any extension * no _files dir is created if no images are to be exported Closes gh-170 (pull request).

Fix protection of special characters on tab completion. Thanks to a patch by Batz (http://github.com/batz), added unit tests. Closes gh-36.

Complete implementation of interactive traceback support. Ever since IPython started, we've had no proper tracebacks for interactively entered code. The terminal version was fairly uncomfortable for more than just a few lines of code, so this was never too big of a deal. But the new architecture allows clients with complex multiline input, and having proper tracebacks becomes now critical for real-world use. Thanks to Robert Kern for key implementation ideas and original patch. Closes gh-177.

added 'don't ask again' option to HTML+PNG inline/external save dialog

color settings from ipythonqt propagate down to the ZMQInteractiveShell in the Kernel

Using R. Kern's code to try to get better tracebacks. It's not quite working yet...
