Request: change link to the comments

[NCKerm]

Description: I use SMF2/TP1.0 beta 5-1.
At my front page I display some forum posts. Under each of these posts there is a link that looks like
"1 comment  | Write Comment".

If would be very handy if the "1 comment" part lead not to the topic itself but to the last unread message, like the link from the "new" button at the board index page.

Thank you!
