Gregory L. Dietsche 31fc1cf9b0 safe-search: restart dnsmasq instead of reload 
Some users have reported that reloading dnsmasq does not always work. It
sometimes stop responding to DNS lookup requests after being reloaded.
This patch changes "safe-search-maintenance" so that it restarts dnsmasq
instead of reloading it.
