Help? there is no help!
dont try to enforce entering a length and some other minor changes
removed mastermind-qt.pro.user, useless.
made spinGuess uses IBeam cursor and window un-resizeable.
use arc4random(), remove anotherround(), move new game stuff into action_newgame(), use QMessageBox correctly (thanks mh!), check for edge cases better, make guess checking more robust and better(?) strings, show mistakes 'X' in red and disallow resizing.
