Add WebSocket announce listener to both IRC bot plugins

- Limnoria: add wsUrl, announceChannel config; __init__, die, _ws_listener
- Sopel: add ws_url, announce_channel config; setup/shutdown, _ws_listener
- Feature parity: subscribe to WS, receive announce msgs, send to IRC channel
- Deferred websocket-client import to avoid load failure if not installed
