Modularization

[gdude2002]

Cozy is currently very coupled. Extensions need to be factored out into modules, and made generic enough that they'd be easy to slot into a KordEx bot that isn't intended only for Quilt.

We can likely get away with using Gradle submodules for this pretty easily.

Alright, so it's time to start looking into this. These are the modules I have planned right now, as a first step for moving functionality out of Quilt-specific extensions:

• GitHub (this will probably just be an API module)
• Logging (message logs, pk first-use logging, configuration of logging channel types)
• Moderation (filtering, locking)
• PluralKit (wrapping events, mostly)
• Suggestions
• Thread Management (e.g. util commands, removing thread status messages, moderator pings)
• Thread Ownership (this one could be reeeeeaal tricky)
• User Management (ban syncing, user clean-up, fix mute role)

So, yup, there's a lot to do!
