Say which camera profile a photograph renders through, and offer to copy it

The info panel gains a line under the lens: "Adobe Standard · in the
file", the .dcp it came from, "· off" when the photographer switched it
off, or "No camera profile · matrix only" — the ordinary case for a
CR2, worded as a fact rather than a failure. A DNG whose embedded
profile may be copied, for a body with no installed profile, also gets
"Use this profile for every Canon EOS 6D →", which saves it into the
profiles directory; the body's CR2s render through it from their next
decode.

The profiles directory is <data>/profiles, read at start-up on desktop
and Android before anything decodes. The library open path never set
the lens line; it now sets both. Labels: Camera Profile, Use Profile,
Look Amount.
