Create database of h-cards

The plan here is to create a table in the database that has the h-card's base URL (usually be a domain name, but I'd like to also support subdomains and paths), the status of the card (i.e. if someone has requested I do not post their information), a JSON-formatted cell of the parsed mf2 of their h-card, and a timestamp of the row's entry.

Should someone's h-card update to not exactly match the most recently timestamped row for that URL, save it as a new row. This will create a natural history of any changes they've made. The front-facing site will only ever consult the table's most recent row for a given h-card.
