Changelog:

• HAM6: use the original color converted to rgb444 instead of the unmodified original color when choosing the ham operation. Provides better color and detail reproduction.
• HAM6: optional dual pixel error calculation with forward prediction. SET is used more extensively on sharp edges. This feature is experimental.
• DynamicHires and sliced mode: in laced pictures color changes only happen on even lines.
• DynamicHires: speed optimizations, 1D dithering was replaced by a better looking constrained Sierra Lite.
• All modes: dithering propagation factor selection (5%-100%).
• Small bug fixes in the color distance function.
• Updated user interface.
