tox: Update Flask to 0.11.0

Released on May 29th 2016, codename Absinthe.

- Added support to serializing top-level arrays to
  :func:`flask.jsonify`. This introduces a security risk in ancient
  browsers. See :ref:`json-security` for details.
- Added before_render_template signal.
- Added `**kwargs` to :meth:`flask.Test.test_client` to support passing
  additional keyword arguments to the constructor of
  :attr:`flask.Flask.test_client_class`.
- Added ``SESSION_REFRESH_EACH_REQUEST`` config key that controls the
  set-cookie behavior.  If set to ``True`` a permanent session will be
  refreshed each request and get their lifetime extended, if set to
  ``False`` it will only be modified if the session actually modifies.
  Non permanent sessions are not affected by this and will always
  expire if the browser window closes.
- Made Flask support custom JSON mimetypes for incoming data.
- Added support for returning tuples in the form ``(response, headers)``
  from a view function.
- Added :meth:`flask.Config.from_json`.
- Added :attr:`flask.Flask.config_class`.
- Added :meth:`flask.config.Config.get_namespace`.
- Templates are no longer automatically reloaded outside of debug mode.
  This can be configured with the new ``TEMPLATES_AUTO_RELOAD`` config
  key.
- Added a workaround for a limitation in Python 3.3's namespace loader.
- Added support for explicit root paths when using Python 3.3's
  namespace packages.
- Added :command:`flask` and the ``flask.cli`` module to start the local
  debug server through the click CLI system. This is recommended over
  the old ``flask.run()`` method as it works faster and more reliable
  due to a different design and also replaces ``Flask-Script``.
- Error handlers that match specific classes are now checked first,
  thereby allowing catching exceptions that are subclasses of HTTP
  exceptions (in ``werkzeug.exceptions``).  This makes it possible
  for an extension author to create exceptions that will by default
  result in the HTTP error of their choosing, but may be caught with
  a custom error handler if desired.
- Added :meth:`flask.Config.from_mapping`.
- Flask will now log by default even if debug is disabled. The log
  format is now hardcoded but the default log handling can be disabled
  through the ``LOGGER_HANDLER_POLICY`` configuration key.
- Removed deprecated module functionality.
- Added the ``EXPLAIN_TEMPLATE_LOADING`` config flag which when enabled
  will instruct Flask to explain how it locates templates. This should
  help users debug when the wrong templates are loaded.
- Enforce blueprint handling in the order they were registered for
  template loading.
- Ported test suite to py.test.
- Deprecated ``request.json`` in favour of ``request.get_json()``.
- Add "pretty" and "compressed" separators definitions in jsonify()
  method.
  Reduces JSON response size when JSONIFY_PRETTYPRINT_REGULAR=False by
  removing unnecessary white space included by default after separators.
- JSON responses are now terminated with a newline character, because it
  is a convention that UNIX text files end with a newline and some
  clients don't deal well when this newline is missing. See
  pallets/flask#1262 -- this came up originally
  as a part of https://github.com/kennethreitz/httpbin/issues/168
- The automatically provided ``OPTIONS`` method is now correctly
  disabled if the user registered an overriding rule with the
  lowercase-version ``options``.
- ``flask.json.jsonify`` now supports the ``datetime.date`` type.
- Don't leak exception info of already catched exceptions to context
  teardown handlers.
- Allow custom Jinja environment subclasses.
- ``flask.g`` now has ``pop()`` and ``setdefault`` methods.
- Turn on autoescape for ``flask.templating.render_template_string`` by
  default.
- ``flask.ext`` is now deprecated.
- ``send_from_directory`` now raises BadRequest if the filename is
  invalid on the server OS.
- Added the ``JSONIFY_MIMETYPE`` configuration variable.
- Exceptions during teardown handling will no longer leave bad
  application contexts lingering around.
