error if component is not required

[catmando]

Say you do this:

React.render(React.create_element(MyFatComponent), Element['div.navigation'])

and you forget to require 'my_fat_component' Nothing happens, and there are no errors or warnings.

Instead the create_element binding (and similar) should make sure the constant does exist and responds to render.
