dns backend reloads/restarts
* add support for the 'null' blocking variant in dnsmasq
(via addn-hosts), which may provide better response times
in dnsmasq

* major performance boost: add a flexible 'Download Queue' to handle
downloads & list processing in parallel, default queue size is '4',
you can raise this e.g. to '8' or '16' to get it really fast
