Complete implementation of interactive traceback support....

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.
