Added a multiple line interpreter for Android version:
cs
CrossLocalNotifications.Current.Show("Test", "This is a test notification"+ System.Environment.NewLine
+ "that has multiple lines"+ System.Environment.NewLine
+ "and so on ..." + System.Environment.NewLine
+ "with a summary",2);
will create a InboxStyle notification in Android where the top min(N-1,5) lines will be added as inbox lines and the last (if exist) will be set as summary text.
PS: also applied a PR fix for reopen issues (credit to @gadzair): original PR [here](https://github.com/edsnider/Xamarin.Plugins/pull/29).
