The optional "setorder" option of a Traits.Model was ignored.
Removed a console.warn
ValueError and TypeError exceptions was not caught by the Traits.Model when using "catchErrors: true" for properties defined with the "set_xxx" and "get_xxx" syntax.

Now the exceptions are handled the same way, regardless of declaring a property using a trait or "set_xxx"/"get_xxx" methods.
Removed an ignored, left-over, trait definition of ControlModels.Date
