dmarc: new DMARC plugin

uses dmarc_httpd from Mail::DMARC for processing and reporting

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
dmarc: s/transaction.header.remove_header/transaction.remove_header/
config/*: mass adjustments
config/plugins: populate it
geoip: enable distance & too_far
headers: disable reject
config-plugins: back out karma.ini
config/plugins: replace mail_from.access and rcpt_to.access with access
config: remove spamexperts from mf.bl_re
Steven's dkim_verify WIP
dkim_verify: commented out console.log messages

so it'll run under Haraka
dns_utils: added get_a
watch: imported to new branch
watch/server: wrap loading of connect and ws in try

and log error if they can't be loaded
watch: only load hooks when ws & connect load successfully
watch: moved port & ssl settings into watch.ini
watch: TLS off until explicitely enabled
