    plug-ins: Use pygobject's auto GValue coversion
    
    In the previous commit, we introuced API that lets us use an array of
    `GValue`s rather than a `GimpValueArray` to make the bindings feel more
    native. In this commit, we go a step further and use the ability of
    pygobject to do automatic GValue conversion to make the API even
    simpler (note that this possibly might not work in each language binding
    though).
