[PATCH v4 1/3] update-unicode.sh: automatically download newer definition files

[Beat Bolli <dev+git@drbeat.li>]

Checking just for the unicode data files' existence is not sufficient;
we should also download them if a newer version exists on the Unicode
consortium's servers. Option -N of wget does this nicely for us.
