polls: last post time

[LCHIEN]

Ever notice how on a poll the last post time is upated whenever someone answers the poll, but the last poster remains the last person who actually posted a reply to the thread. Keeps throwing me, I see a new post time so I look at the last post using the little shortcut thingy and I keep seeing the last post which may be quite old.

Maybe not a bug but it throws me all the time.
