Bounding boxes at zoom levels < 14 should be bigger #22

Right now they are derived from tiles at zoom level 16 which makes them tiny and also makes a lot of them at high zoom levels - this makes browsers slow.

Need to do something like: tile at zoom level X contains bounding boxes of changes on tile X + 2.
