qmd: improves edge case where relaying client sends to local

domaind and removes assumption that qmd is the only active rcpt_to plugin.

Handles the edge case by saving a connection note when the MAIL FROM domain is local. When that is detected in the RCPT phase, and the client has relaying privileges, then the recipient is OK'ed.
qmd: load config at register, with cb
IPv6 support for outbound
connection: fix improper remove_header path
connection: s/transaction.header.add_header/transaction.add_header/
connection: fix bug in config name

docs say early_talker.pause, config/early_talker.pause exists, make code match docs.
Merge branch 'master' of github.com:baudehlo/Haraka
early: support the documented behavior and previous undocumented legacy behavior
Document outbound.ipv6_enabled
