refactored several classes to simplify code
FishSpec and GameSpec - removed unused properties
GameView - refactored the paintComponent method
GameModel - removed unused variables 
ScriptWindow - removed unused widgets
sounds/background/water3.wav trimmed away the errant silence
updated version number to 1.0.5 to reflect refactoring
Also, the GameSpec has been simplified so it might not work well on
scripts generated in early versions...
