Add new '%autoreload 3' option
Example: When an IPython session is ran with the 'autoreload' extension,
you will now have the option '3' to select which means the following:
1. replicate all functionality from option 2
2. autoload all new funcs/classes/enums/globals from the module
when they're added
3. autoload all newly imported funcs/classes/enums/globals
from external modules
Try ``%autoreload 3`` in an IPython session
after running ``%load_ext autoreload``
For more information please see unit test -
extensions/tests/test_autoreload.py : 'test_autoload_newly_added_objects'
