Changed Sensor icons to be more emotionally sensitive (#32904)

The existing sensor icons, while descriptive - dead = dead - are perhaps too matter of fact and don't accurately convey the tragedy. I changed emoticon-dead-outline to emoticon-cry-outline, as I think it better conveys the reality of the situation along with the emotions tied to the statistic.
