983be19e14 Made EvalError serializable because errors can be cell values and need to be saved. 
Turned is* functions into controls, since they have to be able to test errors, and only controls can do that, not functions.
Polished display of errors in cells and in expression preview dialog.

4ed7b45e41 Don't use schema restriction for protograph link suggest because it's not a "soft" restriction (so if the user wants a property that doesn't belong to the type, there is no way to get it). 
More expression functions and controls.
