Make OSM tile server configurable.

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.
