v1.0.4

Fixed

• The bot no longer answers messages a human teammate already handled. A
  conversation that spent time with human support and later re-entered the
  bot's scope looked entirely unread to it, and it re-litigated an
  already-resolved problem past the customer saying goodbye. Customer messages
  at or before the last human teammate reply are now absorbed as handled;
  workflow bots (like the "replies in under 3m" auto-responder) deliberately do
  not count as teammates. (#31)
