added a paramter to allow/disallow page transation for exams
Browsers support automatic translation of a page to multiple languages. Sometimes, this is not desired, especially in certain exams. The change makes it possible to specify that translation is not wanted.
Fixed achieved points in exam statistics per question
In the listing "Exam Statistics per Question", only the automatically computed achieved points were listed, but in case the points were later changed manually, the manual points were ignored. Many thanks to Markus Moser for the report.
