OneSignal improvements

[aaronczichon]

Two OneSignal changes:

• Changed init function to support notificationOpenedCallback as an optional parameter
• Removed platform specification

Hey there,

Why did you change the Promise to a Callback?

Is it because that callback gets triggered multiple times? If that's the case we can convert the return type to an Observable instead.

Hi,

yes it's not trigged during the application run. It's triggered when a notification was received, which can be occures multiple times. Observable could be a solution.

@Corova({
  observable: true
})
static methodName(): Observable<any> {return; }

Changed it to an observable.
