[mkgmap-dev] Configuration for overview map

You were right Gerd, the overlay lines also stopped the mkgmap process.

I would suggest to check all line types specified in the overlay file, then compare it with the invalid lines in the line style
Report all invalid types (without those specified in the overlay file) only as warning message instead of a severe error that stops processing
