Generate man pages using pandoc as part of "make dist"
Add a fake do-nothing man/man3/*.3 target to make "make all" happy
Apparently there's no need for the .PHONY bit (which I misspelled as .PHONE)
Tweak generated man page to only indent code blocks by 4 spaces (not 8)
Reformat all code so it doesn't go past column 80
Make sure dist includes all files in t/ dir
Update Changes.md to mention man pages
Include maxmind-db dir in dist
More updates for distro tarball
