Allow mirroring / propagating messages from discord channel

[BurnySc2]

The purpose is to have one main channel where a discussion is happening and have it being redirected to channels from other discord channels.

This feature needs to have an input channel (server + channel) and a list of output channels (server + channel). Alternatively discord webhooks can also be used for output channels.

Would the list of channels be hardcoded? The problem might be when messages are being edited or updated - how would that be handled?
