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.
Fix wrong view in EventAdapter's ViewHolder impl.
Fix spacing in list_pulse_item.xml
