Updated .gitignore to ignore the out/ build directory.
Code refactor: changed SharedPreferences.Editor…commit() to apply(). No need to commit since we aren't doing anything with the return value.
Code cleanup/refactoring: Implemented the ViewHolder pattern in the NewsAdapter class. This should help make scrolling a bit smoother.

We'll need to do this in all Adapters if it hasn't been done yet.
Set the MainActivity view pager's off screen page limit to 2.
