Backport PR : MAINT: Update locate_profile import to avoid warning...

Backport PR : MAINT: Update locate_profile import to avoid warning Description Currently `IPython.core.history.HistoryAccessor` throws a `UserWarning` upon creation due to an import of `locate_profile`. I realize I can silence the warning in my application but figured this deserved a quick fix. ``` UserWarning: locate_profile has moved to the IPython.paths module since IPython 4.0. return os.path.join(locate_profile(profile), 'history.sqlite') ``` Signed-off-by: Thomas Kluyver <thomas@kluyver.me.uk>

      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.
