luci-app-adblock: sync with adblock 3.5.4

backend:
* add low priority mode (nice level 10), disabled by default
* enhance 'Force DNS' to redirect ports 53, 853 and 5353

frontend:
* switch to dynamic XHR polling for runtime information and logfile
viewing
* add new 'Refresh' button to reload blocklists
* various cleanups & small fixes
