Czywor has an identity now!

Finally, also Czywor has its own voice and sprites.
(Dmewor and Exxwor are still waiting to undergo the same treatment, but it's likely that Baqwor will be completely redesigned, first.)

CHANGELOG

• Extended/modified palette.
• Touched up graphics.
• Added Czywor own sprite graphics.
• Given Czywor a new (and appropriate) voice.
• Fixed muting of wors voices at the very beginning of a game.
