Break reference cycle created by default in Flask instances. 
Flask instances with static folders were creating a reference cycle
via their "static" view function (which held a strong reference back
to the Flask instance to call its `send_static_file` method). This
prevented CPython from freeing the memory for a Flask instance
when all external references to it were released.

Now use a weakref for the back reference to avoid this.
