Work to address the review comments on Fernando's branch. * Added comment about Magic(object) (r1224) * Moved InteractiveTB.set_mode from IPythonApp -> InteractiveShell (r1229) * Moved pylabtools.py to IPython/lib (r1229) * Cleaned up comments and copyrights in testing (r1233) * Added comment about ip.shell._ofind (r1237) * Removed "Bye." from quitter (r1240). * Refactored and removed :mod:`IPython.utils.genutils` and :mod:`IPython.utils.platutils`. These modules have been replaced by topical focused modules in :mod:`IPython.utils`. * Refactored tests in :mod:`IPython.utils.tests`. * Moved :func:`IPython.testing.tools.temp_pyfile` to :mod:`IPython.utils.io`. * Moved :func:`IPython.testing.tools.cmd2argv` to :func:`IPython.testing.tools.pycmd2argv` and documented the fact that this only works with Python based command line programs. * Created a new :func:`IPython.utils.path.get_ipython_module_path` to use in finding paths to IPython modules.
