Zoom levels in generate-tiles.sh

[johaahlf]

The zoom levels need to be changed in the script generate-tiles.sh to correspond to the raster map at dare.ht.lu.se. In general they need to be one less. Can I do that myself? What does the -B parameter stands for? -Z seems to be min-zoom and -z max-zoom. @klokan

Please - do the modification yourself @johaahlf
