* Rewrote large parts of the code to be more modular and maintainable. There may be some new bugs because of this - please report them through GitHub issues if you encounter any!
* Threads, logs, and snippets are now stored in an SQLite database. The bot will migrate old data on the first run.
* Fixed system messages like pins in DMs being relayed to the thread
* Fixed channels sometimes being created without a category
* Some code clean-up. Please open an issue if you encounter any bugs!
* The bot now throws an error for unknown options in `config.json` (assuming they're typos) and tells you if you haven't configured the token or mail guild id.
