(done) Change arch

[Adamo]

Dynamicly changing arch classes in the editor - as it is in CSbuild - would be great; now when you want to change, say, a hook to manacles, or anything else, you must delete the whole object with all its contents - messages, targets and inside stuff - and make a new one adding the same messages to the same targets, messages and inside stuff; sometimes it might be a lot of work if a desired object sends 20 or 50 different messages.. with dynamicly changing arch classes I would just change a deco without deleting an old one and adding a new one and nothing more.

I was going to say dsb_qswap(id, new_arch) but this is an editor issue, isn't it!
