Changes for a statsdash overhaul

[currycoder]

From jonty:

Another ticket. Sorry. Blame Brendan for routing me through this every time.

This is something Oliver requested a little while back, and which I forgot to advance. It is, accordingly, not urgent but it would be nice to sort whenever anybody has any time (lol).

Oliver is distressed because YoY comparison doesn't account for day of the week, just date, so it ends up comparing Mondays to Sundays and so forth. He wants something more like the leaderboard in the office, which feels like it's going to be a lot more work for statsdash. Please consider the following requests and how viable you think they are.

1. Monthly statsdash: leave unchanged
2. Weekly statsdash: containing everything that's in the daily one. To arrive... probably as soon as it has the data for Sunday? So you get it first thing Monday.
3. Daily network statsdash: - remove geo data and Top Referring Sites and add the top five articles for each site, with PVs and DoD change. This will be a really long list so I am not sure it's going to be possible or desirable.
4. Daily site statsdash: kill y-o-y comparison
