Added possibility to print separate problem from the construction space in the exam mode. You just have to pick up option 'Print As Exam Problem' from already existing menu. Working on the adjustion tables for bubbles printing. Need to do this due to changes in general table tag (more exactly due to changes in table environment associated with table tag).
