Brian Granger e24997b0ba 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 These modules have been replaced by topical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.
