[mkgmap-dev] mkgmap multiple input files

Hi Andrzej,
splitter can do that for you with some limitations. keep-complete will 
only handle first given file to splitter. This is quite useful if you 
give splitter a normal osm-file and a srtm-data-file. So it's merged 
within splitter and you get all data in your tiles.
