Show blocked counts on the Blocking page, and reveal + CNAME on hover

The Blocking page shows how many queries each blocklist, and the rules
together, blocked in the last 24 hours (with statistics on). The + CNAME
button on A/AAAA rows shows when the row is hovered or focused, and
always on touch screens.
