Incorporate Map24 Layer

[euzuro]

Thorsten L. has done the leg work for a new Map24 layer.

See  http://www.map24.com

His original sandbox is /sandbox/thliese/openlayers

you can see his example running here:

 http://dev.openlayers.org/sandbox/thliese/openlayers/examples/map24.html

I (euzuro) have made a copy at /sandbox/euzuro/map24

...where I am making standard OL coding practices updates.

one bug so far with this sandbox is that the zoom rectangle doesnt quite work it recenters correctly the map but doesnt pick the right zoom level

Erik, I'm interested in this - we have some map24 stuff going on right now and I would be able to put some time into working on getting this working. I just tried out your sandbox copy and it seems the zoom levels are reversed and I got a javascript error on first load in FF3 that I can't reproduce, something about this.center not being defined. Not sure if it will be sufficiently implemented for 2.7 or not, but we can give it a shot.
