[omnibox chrome:omnibox] Display answer image urls.

Currently, answer images are displayed as image elements whose src attribute
is set to a data url; the user has no way of obtaining the original
image url. This CL adds an anchor element displaying the image src to the
'Contents & Description & Answer' column.
