Avoid loading readline in the kernel...

Avoid loading readline in the kernel This bit of code was loading readline even when there was no need for it. In a Qt console or notebook, try: 'readline' in sys.modules 'gnureadline' in sys.modules I plan to rework this code more extensively once we've switched to prompt_toolkit, but for now, this little fix should make the kernel start slightly faster.

      Shim to maintain backwards compatibility with old frontend imports.

      We have moved all contents of the old `frontend` subpackage into top-level

      subpackages (`html`, `qt` and `terminal`), and flattened the notebook into

      just `IPython.html`, formerly `IPython.frontend.html.notebook`.

      This will let code that was making `from IPython.frontend...` calls continue

      working, though a warning will be printed.
