The loading mask has been replaced with a loading indicator. On devices
or browser windows with a screen width < 720px the loading indicator
will be rendered above the tabbar at left bottom position. Otherwise it
will appear left aligned inside the tabbar.

 ignoreCaseSensitive, ignoreWhitespaces and ignorePunctuation properties added to question. There was not a better option to simulate the check on the backend except in this way. This property are save in the couchDB. Bugfix in ARSnova.view.speaker.form.TextChecker. the undefined function freetextAnswer() has been replace with setFreetextAnswer() or getFreetextAnswer()

ignoreSensitiveCase.js deleted, new design added ('Which of the following options should be ignored?'...)
