Fixed focus: "none"

When the focus parameter is set to "none" (as described in the documentation), an error was raised.

- added focus field test

needsValidation should return true if it was previously reset
Fixed addListener for onFormSubmit

When adding an onFormSubmit listener via the addListener interface, the listener was not added properly.

There is currently no test case for this, by the way.
Reflected previous fix in the minified Files
Corrected test case for addListener/onFormSubmit.

It was previously passing a nested object instead of a shallow one.
