Fixes for React Native 0.55

[nateabele]

Just got this up and running on React Native 0.55 and React 16. Outside of removing references to NavigationCardStack, NavigationHeader, and NavigationHeaderTitle, the only other change required (in my non-exhaustive test app, anyway) was this patch to makeComponent():

6086,6089c6086
<     return React.createClass({
<       getInitialState: function getInitialState() {
<         return {};
<       },
---
>     return class extends React.Component {
6091c6088,6089
<       onAppReady: onAppReady,
---
>       state = {};
>       onAppReady = onAppReady;
6093c6091
<       componentDidMount: function componentDidMount() {
---
>       componentDidMount() {
6100c6098
<           this.renderer
---
>           this.renderer.bind(this)
6106c6104
<       },
---
>       }
6108c6106
<       renderer: function renderer(onMessage, initialModel) {
---
>       renderer(onMessage, initialModel) {
6111,6112c6109,6110
<         return this.updateModel;
<       },
---
>         return this.updateModel.bind(this);
>       }
6114c6112
<       updateModel: function updateModel(model) {
---
>       updateModel(model) {
6116c6114
<       },
---
>       }
6118c6116
<       render: function render() {
---
>       render() {
6125c6123
<     });
---
>     };

Happy to submit a PR, but obviously this breaks the navigation demo. 😞 Let me know your thoughts. Thanks!
