        * app/core/core-types.h
        * app/core/gimpinterpreterdb.[ch]: implemented GimpInterpreterDB,
        which handles registering and resolving custom plug-in interpreters.

        * app/core/gimp.[ch]: keep a GimpInterpreterDB around.

        * app/config/gimpcoreconfig.[ch]
        * app/config/gimprc-blurbs.h
        * app/dialogs/preferences-dialog.c
        * app/dialogs/user-install-dialog.c
        * app/widgets/gimphelp-ids.h: interpreter-path config stuff.

        * app/plug-in/plug-in.c: use registered interpreters when running
        plug-ins.

        * themes/Default/images/preferences/Makefile.am
        * themes/Default/images/preferences/folders-interp.png: just copied
        folders-plug-ins.png here, need a better one.

        * data/interpreters/default.interp: sample interpreter file info.

        * data/Makefile.am
        * configure.in: add data/interpreters directory.

        * plug-ins/pygimp/Makefile.am: install pygimp.interp, which configures
        the python interpreter to point to the python we were built with. Also
        register the .py extension.

        * etc/gimprc
        * docs/gimprc.5.in: regenerated
