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`....
