Updates the Slack integration page to not describe adding a stream
or topic parameter to the URL query since that's not supported by
the current integration implementation.
Updates the Slack-compatible webhook integration page to have the
extra notes about the integration at the top of the page. Also,
removes the reference to a screenshot of the webhook since there
isn't one.

Also, rewrite it as a block processor, so that it works correctly
inside indented blocks.

This adds a webhook that can be used to interpret standard Slack
payloads. Since there are a ton of existing Slack integrations out
there, having a webhook which can accept standard Slack payloads can
significantly ease transition pains. Obviously this can't do everything
that Slack payloads can (particularly WRT their widgets/interactions),
but we can ingest text and parse out multi-block payloads into a message
relatively reasonably.
