[mkgmap-dev] mkgmap r4025 implements --x-dem-poly option

Hi all,

see http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4025
this is useful if you create a map for a country extract like nepal (nepal-latest.osm.pbf)

Here is a screenshot of a map created with the option --x-dem-poly=nepal.poly 
http://files.mkgmap.org.uk/download/378/nepal-with-poly.jpg

The screenshot also shows some wrong reliefs, and I think I used files without many holes :-(
So, next step is to find out what goes wrong with DEM in low resolutions. This might take longer, 
I hope Frank has an idea.
It seems to be a good idea to use a rather high res for the overview map for now. For the screenshot I used
--x-overview-dem-dist=276160, with --x-overview-dem-dist=88000 the problems are gone and DEM file is still only
~300KB.

I've moved some messages into the logger, so there will be less noise from mkgmap.
