updated ionic and angular-moment to recent versions
added overrides to ionicloading css to get rid of that ugly black box behind text
added constant for ionicloading defaults, added DI variable for moment, and added some code for the file plugin via ng-cordova although theres still alot of work to be done with it.  added
added ionicloading to controller and show/hide when calls are made to get headlines.  this should be adapted in a service however so that the loading spinner implementation can change and not affect everyone using it (ionic loading vs cordova spinner plugin)
