initial - queryNumbeo: added method queryNumbeo and string of all countries
create QueryNumbeo class for making HttpGet calls to Numbeo; also added string of Countries in AddPreferenceActivity
queryNumbeo should work, for some reason gets NullPointer still
queryNumbeo works, puts into String results. had to use AsyncTask.get(1000, MS) to wait for doInBackground to finish
