Fixed :py:class:`~aiohttp.web.StaticResource` not resolving urls when adding them via the internal _routes property.
You had to also add the method to the _allowed_methods property, which is not ideal.
Added :py:meth:`~aiohttp.web.AbstractResource.add_route` and :py:meth:`~aiohttp.web.AbstractResource.register_route` to :py:class:`~aiohttp.web.AbstractResource`. -- by :user:`BlindChickens`.
