adding file for device storage.  currently this uses localstorage under the hood to get and set data into local storage
1.  retrieve sports from device storage service in initalization function and fall back on default sports if none exist.
2.  fixed bug in setSportsData which caused function to return every time
3.  save sports to device after resettings sports
fixed typo in function name when calling sportsdataservice to save data
added TODOS for ionic ready stuff.  also removed sports data initialization since this is no longer available in public api.  when calling get, the service will initalize the data if none is there
changed name of function to get sports
added deviceStorageService to javascript inclusions
