Proposal: allow input props to be set

[prevostc]

I need to add a placeholder prop to the input element.

Ultimately, all React.InputHTMLAttributes<HTMLInputElement> should be supported.

I see 3 ways to do this:

• Enumerate all props that we want to pass down to input: <input placeholder={this.props.placeholder} name={name} .... This has the advantage of passing only valid props down (ref or onChange would be invalid props)
• Add a single prop "inputProps" that gets spread down to the input: <input {...this.props.inputProps} .... Easier to implement but not as safe unless we implement some checks.
• Use a render prop instead of rendering the input ourself: render() { return children({setInputRef})}. Use: <Place ...>{({setInputRef}) => <input ref={setInputRef} placeholder="whatever"/></Place>}. More flexible but changes the API. Also the calling component would be required to be a component instead of a function (ref are forbidden in SFC)

Good idea for the placeholder, I'll take a look this WE.
