- Re-added the SCI0 dithering code. Dithering is disabled by default. Added the 3 dithering modes as an enum (and reorganized them a bit)

- Added 3 config options for dithering in the ini file - mainly for purists (config option "dither_mode"): 0 - disabled, 1 - 16 color dithering (Sierra style) and 2 - 256 color dithering
- Dithering is now always applied depending on the screen scale (removed the relevant parameter)
- Removed the background picture buffering option, used to speed-up room changes. Room changing is quite fast (instantaneous), and the extra memory allocated is not worth the possible speed increase in small devices. Plus.... there is no reliable value to set this option to, so there is no point in letting the user decide what value to put there using guesswork
