minor jQuery lesson to (my)self: the original timer triggered buttons by binding changes to submit. This meant that gridbuttons.html button elements didn't cause a sbumit event, or did it twice, with the result of reset countdown function being triggered twice. If the form bind trigger is changed to a 'change' event (as is used for detecting guessed and skipped questions) then the button class events cause a page reload, while 'input type = button' merely triggers the button halt. as the buttons are labelled in this commit is indicative of these functions. HOWEVER start game no longer reveals the statments to be guessed
