* configure.in: add plug-ins/AlienMap2/Makefile to AC_OUTPUT

* libgimp/gimp.c: setlocale (LC_NUMERIC, "C") in gimp_main
so floats are sane over the wire

* libgimp/stdplugins-intl.h: same for INIT_I18N_UI()

* plug-ins/common/color_enhance.c: no literal newlines in string for
portability

* plug-ins/sel2path/sel2path.c: i18n patch from SHIRASAKI Yasuhiro
