sql: Implement bot state

Allows for persistent, dynamic storage of configuration options outside
of the config.json file.

The bot_state table is, essentially, a key-value store for config
options. There are two new prepared statements, `state` and
`update_state`:

- `state` will return the value for the provided key
- `update_state` will create the key or update an existing key
