Noisy output on exit on Windows

[MusicOnline]

When running AutoShardedBot (which Botto uses) then exiting on Windows, you may get an exception such as follows:

Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x00000181F2917EE0>
Traceback (most recent call last):
  File "c:\users\music\appdata\local\programs\python\python38\Lib\asyncio\proactor_events.py", line 116, in __del__
    self.close()
  File "c:\users\music\appdata\local\programs\python\python38\Lib\asyncio\proactor_events.py", line 108, in close
    self._loop.call_soon(self._call_connection_lost, None)

    raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed

This is an issue with aiohttp, as seen in aio-libs/aiohttp#4324.
This error does not affect Botto in anyway, just that it only creates a dissatisfying output on exiting the process. It can be safely ignored.

Nonetheless, you should opt to host bots on a Unix server instead. You can test Botto using Docker when developing on a Windows machine, then host it in a Docker container or push it to your production server.
