Shaperilio/autoreload verbosity (#13774)...

Shaperilio/autoreload verbosity (#13774) Worked on three things: 1. More descriptive parameter names for `%autoreload`; `now`, `off`, `explicit`, `all`, `complete`. (This last one could probably use a better name, but I couldn't think of anything better based on the message in 1d3018a93e98ad55f41d4419f835b738de80e1b7) 2. New optional arguments for `%autoreload` allow displaying the names of modules that are reloaded. Use `--print` or `-p` to use `print` statements, or `--log` / `-l` to log at `INFO` level. 3. `%aimport` can parse whitelist/blacklist modules on the same line, e.g. `%aimport os, -math` now works. `%autoreload` and will also now raise a `ValueError` if the parameter is invalid. I suppose a bit more verification could be done for input to `%aimport`....

      """Minimal script to reproduce our nasty reference counting bug.

      The problem is related to https://github.com/ipython/ipython/issues/141

      The original fix for that appeared to work, but John D. Hunter found a

      matplotlib example which, when run twice in a row, would break.  The problem

      were references held by open figures to internals of Tkinter.

      This code reproduces the problem that John saw, without matplotlib.

      This script is meant to be called by other parts of the test suite that call it

      via %run as if it were executed interactively by the user. As of 2011-05-29,

      test_run.py calls it.
