Allow Textfield error to be of node type

[Gregoor]

In case you want to display a link in the error message.

PropTypes.node seems to be the right thing to use then to allow all sort of "rendering" elements.

[Gregoor]

Oh, I did not know this type existed. thanks, will change!
Edit: But wouldn't the type node exclude a string? Well same probably goes for object.
Edit2: Of course, I forgot we have .oneOfType!

From the doc

// Anything that can be rendered: numbers, strings, elements or an array
// (or fragment) containing these types.
optionalNode: React.PropTypes.node,

So only node is enough. Also, could you please squash your commits please?

[Gregoor]

It took a while but I think I squashed it. Always grateful for a chance to work on my git skills.

perfect! :) Thanks @Gregoor
