Subject: [PATCH] pass SSR context

This PR concerns this issue on FlowRouter : https://github.com/kadirahq/flow-router/issues/205

When ReactLayout.render is called asynchronousely, the ssr context is not accessible anymore. This is a double PR (I'ma making the same for DocHead). It just add the context as an optionnal parametter of the render and _addToHead functions.

So in the action hook of the route constructor in flow router, you can now do this :

	action( params, queryParams ) {

		let context;
		if ( Meteor.isServer )
			context = FlowRouter.ssrContext.get();

		Meteor.call( 'getAsyncData', ( err, data ) => {

			DocHead.setTitle( data.title, context );

			DocHead.addMeta( {
				name: 'description',
				content: data.description
			}, context );

			ReactLayout.render( ReactLayouts.MainLayout, {
				content: <ReactView.MyView data={ data } />,
			}, context );

		} );

	}

There's probably a smarter way, but this one works.
