Steven's dkim_verify WIP
dkim_verify: commented out console.log messages

so it'll run under Haraka
dmarc: new DMARC plugin

uses dmarc_httpd from Mail::DMARC for processing and reporting
connection.js: save A-R header after data_post

so DKIM and DMARC plugins get a chance to update it
spf: store SPF results in ResultStore (was notes)
dmarc: save results in 'results' (was in a note)
dmarc: cleanup rebase litter
dmarc: use new boolean config option
dmarc: add intermediate header in cmd_data, and update

in data_post_respond if new results
dns_utils: added get_a
access: for 'any' list, don't process when org_domain not discoverable

and skip ipv4 literals during HELO
cleanups: remove docs for deprecated plugins
dnsbl: use boolean config, use callback to refresh, make tests pass when extra DNSBLs are configured
connection: fix bug in config name

docs say early_talker.pause, config/early_talker.pause exists, make code match docs.
geoip: fail gracefully if geoip-lite isn't installed
graph: handle 'sqlite3' not installed gracefully
data.headers: fail gracefull if address-rfc2822 not installed
net_utils: s/stun/vs-stun/

vs-stun:
  works with current versions of node.js
  has a nicer API
  provides more net topology data (we don't need it, but nice to have)
package.json: s/stun/vs-stun/, added redis as optional dep
qmd: rename test filename (to match every others one with a .js ext)
