Update NanoUI Live Map.

* Simplified how items are positioned on the map (e.g. ((value.x - 1) * 8) is now just value.x, scaling is applied later).
* Added four zoom levels (x1.0 to x2.5, triggered by links in the template).
* Moved the "Generate NanoUI Map" into the Server tab, to prevent it being used by admins accidentally.
