[mkgmap-dev] Fix for mkgmap --version

Hi, for me, mkgmap --version never worked. Now I found the reason: Some JRE comes with an own "version.properties" file, which of course is incompatible to the mkgmap one. Thus mkgmap --version did always print only "svn". I think the easiest way to solve the file conflict is to rename the mkgmap version to "mkgmap-version.properties". Patch attached, this one fixes the problem for me.
