- all uci rules are boxed in custom chains now, so a firewall stop leaves user rules intact
	- properly handle selective ipv4 or ipv6 only firewall start/stop/restart actions
	- support ip ranges (e.g. option src_ip '!192.168.1.1-192.168.1.100' -> -m iprange ! --src-range 192.168.1.1-192.168.1.100')
	- support time options (e.g. option weekdays 'Mon Tue Sat' -> -m time --weekdays 1,2,6')
