showPermanent method

Hey, such great component, thank you.

By the way, I need to fully control displaying toast, so I made little changes, just added showPermanent method. This could be a cool feature in your package.

Best regards, john

this.refs.toast.show('hello world!', DURATION.FOREVER);

 // later on:
 this.refs.toast.close('hello world!');
