This patch makes it possible to configure the tile server used for serving the OpenStreetMap maps. Add README with hints about the Tile Usage Policy (http://wiki.openstreetmap.org/wiki/Tile_usage_policy). A list of public available tile servers can be found here: http://wiki.openstreetmap.org/wiki/TMS You can also configure the default zoom level.
