aiohttp 3.1.0 release

Welcome to aiohttp 3.1 release.

This is an incremental release, fully backward compatible with aiohttp 3.0.

But we have added several new features.

The most visible one is app.add_routes() (an alias for existing
app.router.add_routes(). The addition is very important because
all aiohttp docs now uses app.add_routes() call in code
snippets. All your existing code still do register routes / resource
without any warning but you've got the idea for a favorite way: noisy
app.router.add_get() is replaced by app.add_routes().

The library does not make a preference between decorators::

routes = web.RouteTableDef()

routes.get('/')
async def hello(request):
return web.Response(text="Hello, world")

app.add_routes(routes)

and route tables as a list::

async def hello(request):
return web.Response(text="Hello, world")

app.add_routes([web.get('/', hello)])

Both ways are equal, user may decide basing on own code taste.

Also we have a lot of minor features, bug fixes and documentation
updates, see below.
