Show template usage for all time on it’s own page

> We show the last weeks template usage on the dashboard, which is
> great, but if you're looking for longer term trends, you're out of
> luck...

> So, let's let you see more on a more detailed page (linked from the
> dashboard). Initially this should just show you all templates that you
> have used ever and the count for each. Order same as dashboard, most
> popular first.
