Shouldn't short? be compatible with short?

[derekgreer]

I'm running into an error which seems to stem from the decision made on this line of code:

WestwindToolkit/Westwind.Data/CommonClasses/Support/DynamicQuery.cs

Line 1738 in 29b35a2

if (st != source && tt == target) return false;

IsCompatibleWith(typeof(short?), typeof(short)) returns false. The intent of the method seems to be to see if a short is compatible with an int, etc., but doesn't account for whether short? is compatible with short.
