[WIP] Statistics design

We create a more readable page for stats. At the moment, it's basic. But we prefer be sure to do it well.
I dont' know for others pods, but framasphere's users like check stats :)

I don't think the "Connection to" prefix is necessary, I'd vote to drop it, leaving just the service name in the title.
