Related to T7829. feed.query's after/before parameters seems to be feed-relative, not time-relative. Before a chrono key means later in time (at least by my testing). The notification.channels setting was not being used, all joined channels were receiving messages. If a large number of messages come in at once, the bot may be disconnected for filling RecvQ of the IRC server. Added a sleep of increasing length, similar to behavior of IRC clients and bulk pastes. Add documentation of notifications.verbosity

manual testing
