Create new interface AnswerLogging and implementation
these classes are used in the layouts to log the answers and save them as json
in the main activity on the onDestroy method could the json be returned or send to a server
adjust the edittext submit - used setOnEditorActionListener to listen for the IME ACTION DONE action
changed Toasts to log debug mode
create new method submit for the edittext submission
done action calls next button on click method
fix orientation bug in json und Radio Entity
also fix RadioQuestion next click bug - adjust button next id to 0xFF231 
the id 1 was already in use so the listener was added to the wrong button
removed unused imports
