to allow loading indicators and other use cases.

William Casarin 4ad483090e feat(NIP-01): Implement limit 
This was quickly sneaked in by fiatjaf per my request[0], it makes many
queries more efficient and allows for paging when combined with until.

It is a bit weird to have multiple limits on each filter... for now we
just choose any or the last limit seen.

Greg Heartsfield 234a8ba0ac feat: limit event publishing to NIP-05 verified users 
This adds a new configurable feature to restrict event publishing to
only users with NIP-05 verified metadata.  Domains can be whitelisted
or blacklisted.  Verification expiration and schedules are
configurable.

This upgrades the database to add a table for tracking verification
records.

Greg Heartsfield 98c6fa6f39 feat: allow whitelisting of pubkeys for new events 
This adds a configuration option, `authorization.pubkey_whitelist`
which is an array of pubkeys that are allowed to publish events on
this relay.

Greg Heartsfield af453548ee feat: allow author and event id prefix search 
This is an experimental non-NIP feature that allows a subscription
filter to include a prefix for authors and events.

Greg Heartsfield 2d28a95ff7 feat: allow arbitrary tag queries 
This is an experimental feature, outside of any NIP, that demonstrates
generic tag queries.

Instead of limiting subscription filters to just querying only "e" or
"p" tags (via `#e` or `#p` attributes), any tag can be queried.

As an example, consider an event which uses a tag "url".  With this
modification, a subscription filter could add a top-level field
"#url", with an array of strings as the key.  Exact matches would be
returned.

A NIP is forthcoming to formalize this.

Greg Heartsfield d72e7a57b6 feat: hide older metadata update events 
This updates the database schema to support hiding events.  In this
case, we are hiding older metadata updates when an author provides an
updated event.

Greg Heartsfield 5b6a20dfa6 feat: remove author from subscriptions (NIP-01 Spec) 
The `authors` field is sufficient to represent all queries that
`author` could have been used in.  See
https://github.com/fiatjaf/nostr/issues/34 for the discussion leading
to this removal.

Greg Heartsfield 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.
