Title: Validate UpdateDataExpressions: enforce that they either specify AllRows...

Enforce that UpdateDataExpressions either specify AllRows or a nonempty Where (but not both). This came up when I was first using FM to update a bunch of rows -- I didn't specify either of the above, expecting it to work like SQL, and the end result was a nasty NRE.
