WIP on comments: band-aid for issue #39

This is not an ideal solution. Copying over all the comments in
Javascript is not really the best place to solve this issue. But
until I can find time to understand the PHP mapper and DTO code
better and work out where the comments are getting clobbered in
the PHP mapper/DTO process, this band-aid will at least do what we
need for now: preserve existing comments when answers are edited.
