    app: migrate configuration files for s/Blend/Gradient/ tool renaming.
    
    This includes migrating properly any custom shortcut (menurc), as well
    as a few strings in tool-presets/, and finally "gimp-blend-tool" in
    contextrc and devicerc.
    File toolrc also has some occurrences, but we are already skipping it
    anyway, same as whatever is under tool-options/.
    Hopefully I missed nothing.
