Instead of using an Arc Mutex for state management embedded directly
into the bot, utilize actor pattern, with the idea that this will be
much more useful than simply logging a message once in the future.
This also refactors the bot code so that instead of a single run_bot
function, the DiceBot struct now has a run() method attached to it.
This also necessitated changes and cleanup to the dicebot main, which
is for the better anyhow.
The error and config types are also now in their own files, and
implemented for more in-depth use cases.
This makes the oldest message age setting optional, in additon to the
entire bot config (for now). If the oldest message age is not
specified (or if the entire bot config is missing), it will default to
15 minutes.
This gives us many things for free, like automated state management,
no need to declare special API structs and use HTTP requests directly,
and most importantly: ENCRYPTION!
