add date answer space

for now, this is just a simple date picker done via the html input type
"date". Unfortunately, that's not supported by Safari, so the rust util
now prints out a warning if it's used.

I'm not sure if there's any other reasonable option which would go
around this that's not "using a web framework" or "hacking a fallback
date picker which just consists of a couple of combo boxes".
