[mkgmap-dev] Splitter: tiles names from geonames

CD> I've seen tiles are named using all the geographic area covered by

Hmm good catch, I hadn't considered that case. Since I was testing on the 
UK (an island), Europe as a whole, and the entire planet, this problem didn't 
crop up! There's a few different ways this could be fixed. I might try ignoring 
cities in parts of the map that don't contain any data, or alternatively 
weighting the country/city selection by the node density - hopefully one 
of those two approaches will give better results.

I'm not sure I'll be able to implement this for at least 3 weeks though. 
I have a very busy week ahead and am then on holiday for two weeks (OSM-based 
maps in hand on my Vista HCx of course!).
