Meteor 1.3

https://github.com/meteor/meteor/issues/5786 Meteor 1.3 is going to use WKWebview by default. And phonegap-plugin-push 1.3.0 use UIWebview under the hood. Can we upgrade this plugin?

```
Cordova.depends({
'phonegap-plugin-push': '1.3.0'
});
```

Start with the Cordova.depends declaration shown in the issue and review the Meteor 1.3 compatibility context in issue 5786. Check the available phonegap-plugin-push versions and verify the selected version works with WKWebView while preserving push notifications; done means the dependency is upgraded and the relevant mobile behavior is confirmed.
