v1.2.0 - Fixes the pink custard

[Edgemaster]

A couple of weeks ago, people started experiencing 'pink custard' due
to the map server at the OS changing. This version fixes that issue.

I am now using the Official OrdnanceSurvey OpenSpace API Tiles (but
using the plain OpenLayers interface, theirs is a bit clunky
otherwise), there is a 30,000 daily tile view limit, just shout at me
if you hit any problems, I can probably work around it.

Advantages of using the official api include a greater range of
scales, the full-uk view is now working correctly, and there is also
an extra zoomed version of the landranger 50k maps, and the rather
oddly presented (imo) 10k scale mapping (which crazily doesn't show
footpaths! :o ).
