Remove UIAlertView before taking the picture. Added an UISegmentControl form language selection. Added a new property - tesseractLanguageSelector -  to PocketReaderDataClass to receive the value of the index of the segment control. Changed the tesseract call to method apertouDois, testing now the value of tesseractLanguageSelector instead of testing the UIAlertView button pressed. Deleted unnecessary method formerly used to test which button of  alertView was pressed. Added new method for handling a change of the UISegmenteControl that defines the language used by the tesseract.
