[mkgmap-dev] Small improvements for house numbers

Hi all, the corrections in r3392 improves the house number code. In some cases a house number was added to the wrong part of a road, sometimes even the wrong side. Possible effect: When you search for a specific number in a street in a specific town in some cases, MapSource shows multiple possible places. Besides wrong OSM data there are many other possible reasons for that, I fixed only one of them until now. The rest is work in progress... Gerd
