react-lazyload2

Hey, jasonslyvia. Too late to updated and fix my issue. So I Publish an version 2.

Fork from react-lazyload

what's different?

• fix 84
• fix 97
• add props target

// target : oneOf([
//     React.PropTypes.func, // which return an html dom
//     React.PropTypes.node, // html dom
// ])
// bind the target scroll event
<LazyLoad ... target={ ... }/>
