* setting up google analytics for angularjs
* added gulp-changed for img, fonts & sounds

* updated JS task so that it replaces config values using underscore, but only on app/js files

* updated JS task so that it does this using streamqueue

* replaced ng-min with ng-annotate

* moved app/js/app.js => application.js because the name of the file
  was preventing the application.js content from showing in the app.js build

* tried getting JS Hint to report relevant things, but no such luck.
