Split React components into logical and representational

[php-coder]

From each component FooForm, we should extract FooFormView that contains only HTML markup. All the methods and state should remain in FooForm and in its render() method should use <FooFormView />

@bahoss Hi, could you apply similar changes to other components? Here is the example: d29390e

A few notes:

• in *View component, we should extract variable from props in the begging of the render()
• don't touch this.props.l10n, leave them as-is (to reduce diff)
• when you modify a line and see that it uses foo={something} you can also add a spaces around: foo={ something } (but don't modify existing code just for that)
