auth_vpopmaild: add tests and CRAM-MD5 auth support
vpopmaild: consolidated config loading logic into register()

with a callback
vpopmaild: added utf8 encoding to socket
qmd: rename test filename (to match every others one with a .js ext)
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

weirdly related enhancements

* move is_ipv4_literal from plugins/helo.checks to net_utils
	so it's available for the SPF plugin

* SPF: skip HELO tests for IP literals

* SPF: when a connection has relaying permissions, use our (Haraka's) public IP in the SPF mail_from query, to determine if Haraka has permisison to send on behalf of that MAIL FROM domain.

* move the public_ip setting out of config/connect.geoip.ini to config/smtp.ini, used by GeoIP and SPF plugins.

* updated connect.geoip to use boolean config options
remove geoip config changes
spf: added [relay]context setting, and defer/deny settings for

helo/mfrom when relaying is set
