        * app/core/gimpenvirontable.[ch]: added some rudimentary support
        to prepend values to existing environment variables. You can do
        "separator name=value" now. API change to gimp_environ_table_add
        for it too. Also added some error checking.

        * app/gui/gui.c: change to new above API

        * plug-ins/pygimp/Makefile.am: write ": PYTHONPATH=" out to env
        file

        * po/POTFILES.in: add gimpenvirontable.c
