incorporated saving new Qs to DB and implemented exiting at any time

Howdy fellow group projectors I've done some tweeking(no, not twerking) and therefore request your eyes to merge my pull request...
update flashcards 1.1 includes:
new feature to SAVE ones questions to database, apologies to any users who have been losing their 'saved questions', this feature should now be working 
new feature exit at ANY time, now when you realise you don't know the answer and don't want to guess, you can exit!
