Added method to close Portals from child component

Added the closePortal method to PortalWrapper's context, so it can be called from the child component.

Example:

class Contents extends React.Component {
  render () {
    return (
      <p>
        <button onClick={this.context.closePortal}>Close me</button>
      </p>
    )
  }
}

Contents.contextTypes = {
  closePortal: PropTypes.func
}

return (
  <Modal trigger={<Link>Open me</Link>}>
    <Contents />
  </Modal>
)
