This PR adds an option to the /join command to let the user provide their own webhook URL, which Scripty will then send message transcriptions to instead of Discord.
My motivation for this is to address the privacy concerns a couple of people have raised concerning leaving a written record of voice conversations in Discord. My plan after this is to set up a web interface for displaying transcriptions (I'm thinking basically just this) so that only participants in the chat can see the messages, and Discord itself never sees them at all. I also think this will be useful for tying into my other goal of summarizing conversations, since this will let my service keep a running summary, rather than having to wait for the entire transcript at the end of the conversation.
