[Development] Mailing list should be more discoverable

[Jiang Jiang]

Hi,

I have suggested this to the web team back in Nokia days, but it
unfortunately never happen (never got any response).

The problem is, after qt-project.org redesign, there is simply not
link to lists.qt-project.org at all, not a single word about the
existence of a mailing list. The wiki link to
http://qt-project.org/wiki/OnlineCommunities doesn't mention anything
about mailing list either. Isn't mailing list a form of online
community?

Please at least put a link on the front page.
