Fixed the visual artifacts in the inventory box curtains in The Vampire
Diaries. Renamed the Shades class to Curtains to reflect their name in
the original engine.
Moved all hardcoded engine data that changes between games (e.g. number
of items, number of event flags) to a dedicated file and added a function for
accessing it in NancyEngine.
Changed the UI::Scrollbar class so it doesn't require subclassing and added functionality for horizontal scrollbars. Fixed the textbox and inventory box scrollbars so their lowest point is consistent with the original engine's.
Class members that get properly initialized after the constructor now also get default values during construction to silence warnings. Also fixed a couple of broken entries in response.cpp that were uncovered by these changes.
Removed the BlitType enum and getBlitType() method from RenderObject, and replaced them with setTransparent(). This was done to reduce redundant code, since ManagedSurface can already pick between a transparent and regular blit depending on whether the provided source surface has a transparent color set. Also added the correct transparent color for The Vampire Diaries, and the transparent color for nancy1 now gets calculated on the fly.
Added initial support for savestates. The format will most likely change with future commits, but I will only start versioning once the engine supports more than a single game. To support proper serialization the Scene state has had its kInit state split into kInit and kInitStatic, InventoryBox had some of its code reordered, and members of several classes have had their types changed.
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.
