Add a filter to the event logs

The event logs would be far more useful if we could filter out entries, e.g. based on users.

At the very least we should have an option to export / download the logs for review.

Actually, filtering is a moot point, as there is already access on a per-entry basis. But exporting the logs would still be useful.

For organization event logs, you can use the API to pull them :slight_smile: - specifically /public/events
