Moved balloons management into Gfx, which is now responsible for positioning and drawing. All balloons are now drawn on a different layer than the game graphics, thus simplifying screen management. Dialogue code has undergone a major revision, and the superior implementation of answer selection in the Amiga version is now used in place of the poor PC one. Other bits (where some changes had already been introduced) have been updated, too.
