Changed the way the correct object is determined based on how the solution is written for transferAndGroup steps. In some cases, the correct object is object1 of the next step, while in other cases, it is object2 of the next step. This change was added because the farmer wasn’t able to give the milk bucket to the cat in the Best Farm texts due to the app detecting the incorrect object.
Adjusted the way menu options are painted for ungroup interactions

Updated versions of best farm and circulatory epubs. The circulatory epub should be close to complete (if not already complete), but the best farm epub is still expecting changes: splitting pages and debugging transference in last story.
