Generate distribution maps for keys on way, too

Until now distribution maps were only generated for keys on nodes. No there are
maps for keys on ways, too. (Not for relations, though). This commit also adds
command line options for tagstats to define the area you want the map for. Its
no longer necessary to recompile tagstats if you want to change this.
This commit does not change the UI/API yet, so you still only get the node map.
