Icons Makefile typo fix
Updated toplevel Makefile to make/install data files
Fixed geonames_process.pl to issue an error if required files are not found
Toplevel Makefile fix to generate ChangeLog
Fixed error messages in geonames_process.pl
geodata.xml is now generated correctly

Data is downloaded from geonames.org, and processed with an AWK and a Perl
script. The result is the part of the distribution, so the average user
(or a packager) doesn't have to download that much of data.
Removed ChangeLog. It is now autogenerated from git logs
