New LayoutXML feature - Linked Entities

[markduk]

With the new LayoutXML feature it would seem that linked entities must have an alias in order to show in the results view. It took a few minutes to work this out. I'd prefer (if possible) for Fetch XML builder to work the way it did by default and I only need to learn the new LayoutXML nuances when I have a need. For now I've turned Layout XML off.
Sorry for turning off your hard work.

I totally agree.
Next release will make this a bit easier to use it. Promise.

There are a bunch of other issues in this area, starting in #771
