Fixed the tileset issue where you and Mom could walk through walls and certain objects.

Added many additional interactions with items in the house. (Full cheat sheet: couch (left side), dining room table, bookshelf in room (center), dresser in room (far right), bed in room, window at back of main room, almost every wall decoration in the main room)

Significant update to final event with substantial dialogue changes and an entirely new branching outcome.
