Set channel names and reply as thread for Discord

Released two features to manage the Discord bot so channels stay clutter-free.

1. You can configure the Discord bot to reply to messages in threads. This keeps conversations neatly grouped, makes threads easier for users to follow, and keeps the main channel clutter-free.

2. You can now set which channels the bot should listen on. If configured, the bot will not reply when someone tags it from other channels. This is useful for making sure the community uses the bot only in designated channels.

You can configure these items from the Discord settings page on your dashboard.
