devel/libtextstyle, devel/gettext*: Update to 0.23

comms/grig, deskutils/xpad, games/7kaa:
Fix problem between autopoint (gettext) and aclocal (automake).
First autopoint installs gettext m4 files in WRKSRC/m4 for the
version of gettext requested in configure.ac. And then aclocal
should use those files. These ports were either missing an "-I m4"
flag so aclocal didn't see the autopoint m4 files but used the ones
from LOCALBASE/share/aclocal, which are the wrong version, or they
used the --install flag that makes aclocal copy files from
LOCALBASE/share/aclocal overwriting the autopoint m4 files.
