Update Fomantic UI v2.9

• Support file inputs https://fomantic-ui.com/elements/input.html#file-input
  • This is automatically supported. Nothing to do.
• Consider supporting custom calendar formats https://fomantic-ui.com/modules/calendar.html#custom-format
  • This would require server side validation, which is out of scope.

Updated to v2.8.8, but updating to v2.9 brings with it a validation error display on page load for required blank fields. Fomantic UI v2.9 has many validation options, which is great, but the way to use them needs more thought.

It seems there is a noNativeValidation option in unreleased 2.9.4 🎉
