Update cordova.android.js to 3.5.1 and add .abignore file.

We used to have a bug in which we generated projects with hardcoded WP8PublisherID and WP8ProductID - see https://github.com/Icenium/Ice/pull/1955. This project unfortunately is one of them. You need to generate new guids and replace the values before committing. You can use Visual Studio's Tools -> Create Guid tool to get new valid Guids.
