v1.2.2

1.2.2

• Consolidated all transport defaults in a single default_transport_config method
• Simplified handling of transport and delivery config defaults
• Moved target_required from transport to delivery config, since could vary per delivery for generic transport
• Added selection_rank for delivery, and made Notify Entity transport resolve last
  • This is to support future resolution of [issue #8]
• Notification now records a missed count, where transport runs without error but makes no deliveries
• NotifyEntity now always auto-generates a default Delivery unless the transport is explicitly disabled
