NEW: devel/libgrapheme

Hi,

this new port contains the suckless unicode library libgrapheme.

pkg/DESCR:
libgrapheme is an extremely simple C99 library providing
utilities for properly handling Unicode strings made up of
user-perceived characters ('grapheme clusters') according to the
Unicode standard. While providing convenience functions to
operate on UTF-8-encoded strings, you can also use libgrapheme
for any other encoding as well.

ok?

bye,
Jan
