Remove "claim badges" per issue #460
Active dropdown menu inherits background(w) and color(b)
Add body classes
title element back to h2 (oops)

so there's some extra redirection to get around that.
Hook up Mozilla Backpack button to do modaless push
Don't show share button if underage
header images in place, span added to h2, challenges title moved to variable
mobile reverts to no background image in title h2
comma added to landing text, ampersand replace with "and"
