adblock config is not available during startup
* fix selective subdomain whitelisting for dnsmasq
* fix a kresd restart issue with 'DNS File Reset'

dns backend reloads/restarts

(via addn-hosts), which may provide better response times
in dnsmasq

the new blocking variants. Search now includes
backups & black-/whitelist as well
