Automatic Database Updates

[ghost]

Would be nice if the plugin could automatically update the databases periodically. There's already code for fetching it, seems like it wouldn't be too outlandish to add an @interval and store a timestamp in the bot.db or something.

Thoughts?

MaxMind defines the update schedule for each database edition, so it's hardly necessary to poll blindly for a new version. The City and ASN editions this plugin uses update "Every Tuesday and Friday".

MaxMind also documents exactly how to check when a database edition was last updated via HEAD request.
