- Bootstrap angular to prevent situations where angular loads before plugins are ready, which caused plugin usage at app start to error out.
- Removed previous workaround to $cordovaNetwork usage since it's not necessary after bootstrapping.
- Removed ngCordova splash screen implementation from app.js. There is a second implementation using a Cordova plugin done thru config.xml. This was not an issue pre-bootstrapping since the ngCordova code didn't get to run, but after bootstrapping the splash screen was showing twice.
