adding suggestion string

[ajcassell]

577 I tried to make this text suggestion only show up when the question pronoun box is selected but this doesn't seem possible in the realm of the matrixdef syntax

If that shows up under every pronoun, that would be suboptimal, I think. What about using validation instead, and showing this as a warning just in case someone enters a string matching one of what, who, where, when in that box?

Alright, I've changed to a warning instead.
