IMAGE: Use palette class in Cinepak decoder.
...
The Cinepak decoder had an unweighted euclidean color distance calculation for palette matching. This was moved and rewritten to a color distance method on the palette class.

IMAGE: Fix undefined behaviours in Cinepak decoder
...
Left shifting a negative number is undefined (as it may eat the sign
bit).
Instead, multiply by 2 which is the same but properly defined.
Also fix the convertYUVToColor function signature as it takes int8
values.

IMAGE: Explicitly initialize CinePak codebooks
...
Starship Titanic produces lots of "uninitialized value" warnings
at the very beginning of the game, when turning right. This is
because in the very first movie frame it uses codebooks that have
not been loaded. Explicitly set their data to 0 to guarantee
consistent behavior.
