bin/comics: add script for updating xkcd, add $state_file config
xkcd is special (read: other than all others scripts) because it does not
contain a timestamp information in the comics. we have to track the last
script that was added to our mirror. so the xkcd script needs a state-file
containing the last xkcd that was mirrored. the date of the xkcd is the
day of the first discovery of a new comic.
