Rewrite fade in / fade out implementation

Browse Source 
Before this change, fade in and fade out was implemented using a
16-steps dithering pattern.

Now fading uses alpha-blending. It behaves like the PC98 version, where
fading was done by palette animation.

This reduces `sizeof(AGS)` by 1.2MB.
