[UI Framework] Reactify basic form components

[cjcenizal]

"Basic" form components are:

• TextInput
• TextArea
• CheckBox <input type="checkbox" className="kuiCheckBox" onChange={ props.onChange } checked={ props.isChecked } />
• Label
• Select

These components can just be simple wrappers around the markup and CSS. A few of them will need a size prop for applying size modifiers.

When we implement these components, we need to make sure we search the examples and update references to them with the new React components.
