Hyperstack results sould have non-spatial dimensions logged in their own Table columns

[mdoube]

I had a good reason not to do it that way. IIRC sorting columns didn't quite work, i.e. results didn't "follow" their channels/frames. However, that is no longer the case.

This fix will be bigger, and should be in another PR. I'm assuming for consistency's sake you want all the plugins to write their results in the way described above?

@mdoube If you wouldn't mind adding an issue about it in the meanwhile?
