Add a new FormValidation class to help make a consistent declarative
field validation pattern for Keyman Developer forms, and apply that
initially to the New Keyboard Project Parameters dialog. This pattern
replaces the earlier EnableControls pattern; ideally we will replace
validation in other forms with similar validation requirements with this
over time.
