49598b2c9e fix: subscription event filtering bugs
Subscriptions properly filter using the authors tag.  Petname/keys are
correctly filtered (previously the event tags were incorrectly used).

1589268eba fix: use database to publish all events
This fixes a race condition where a publisher might send an event, and
immediately after issue a subscription for the same event ID.  Prior
to this change, that event would have been published on the broadcast
channel (and ignored by our publisher, because they had not yet issued
the subscription), but not yet committed to the database.  Their
subscription would trigger a database query which would return zero
results.  Therefore, they would never see the event they published.
The noscl tool is one client that would suffer from this.

Now, all events are broadcast only after they exist in the database,
so a late subscription will always return the event.

23f47899cd feat: broadcast events that match active client subscriptions
A broadcast channel sends messages to all connections.  Any connection
with a subscription that matches then sends it via websocket.
