SpActivationTransform is only references from tests.

I could not know if it is used for something else than testing. If this is the case may be we should move it to the tests package.

this one instead is WIP and I think we need to let it there. I was working on a way to transform what will be transmitted when an activation happens (say you transmit a class but you actually want the methods, or something like that). I am not sure it will remain as is, but for now I would let it there. (but we can keep this issue alive so I do not forget to clean this when I finally have time to finish that)
