Fixed a lot of code formatting issues, including switch case statements being indented, some curly braces not being left hanging, if and for statements not being surrounded by newlines, some double spaces, and more.
The original engine has two secret debug/cheat dialogs: one for general data (timers, current scene, inventory), and one for event flags. I decided to implement them as I find them much more useful than just using debug commands, particularly since they contain descriptions of every event flag and inventory item (this data is pulled directly from the executable's embedded resources, albeit in a slightly hacky way). Also, I've decided not to implement the slider puzzle tab present in nancy1 since I have no use for it.
Rewrote most of the engine using a much more object-oriented approach and using more of ScummVM's common classes. This design deviates quite a lot from the original engine's, but should be more maintainable and extensible in the future.
Added a playerTime variable, which contains the in-game time, and expanded the Time struct to support it; also added the timeOfDay variable which can affect scene changing.
