        * glom/data_structure/field.cc: sql(): Move text escaping code into
        glom_escape_text() so it can be reused. For IMAGE fields, assume that
        get_binary() is already the escaped binary format, but escape it
        again as text, so we get the \ needed for SQL commands.
        * glom/data_structure/glomconversions.cc: get_escaped_binary_data():
        Use one \, not \ to separate byte numbers, because that's the format
        used by get/set_binary() in libgda at the moment.
        * glom/utility_widgets/imageglom.cc:
        get_value(): Use GlomConversions::get_escaped_binary_data() before
        set_binary() because Glom must assume elsewhere that it is escaped
        in all GdaValues. This workaround will all be unnecessary in libgda-2.0,
        which properly unescapes binary buffers.
        Images are now saved properly into examples, and inserted properly into
        the new databases that are created when examples are opened.
