[gimp] Bug 600554 - Implement layer group transforms

    Bug 600554 - Implement layer group transforms
    
    Same fix for the PDB: if the item to transform is a group layer, call
    gimp_item_transform()/rotate()/... directly instead of going through
    the wrong cut/transform/paste code path.
