Changed setups so that they can be applied to a specific page in the PhysicalManipulationActivity instead of the whole chapter.
Allow user to move on to next sentence if the current action sentence has 0 solution steps. Normally if a sentence has no solution steps, it is not considered an action sentence, but there is one sentence in the circulation texts where the user must perform an action in real life (rather than in the application). In the future, it might be better to give that particular sentence a separate class and color it differently.
Updated versions of all four epubs. Farm and House have been updated to reflect page-specific setup changes. Best Farm is mostly functioning but still requires changes. Circulatory still needs work.
