Commodore64: Renamed Sprite to SpriteGenerator. Created GraphicsGenerator file, with plans to isolate the background graphics generation (as it is a separate logical unit within the chip itself.)

Fix some compiler warnings. Border is still odd, needs the other half of the border unit logic. Also, a marginal performance boost from sealing classes.

Video chip timing in the old core now builds its timing tables dynamically instead of having them hardcoded- should greatly reduce human error. The algorithm should cover every single revision of VIC.
