made 96 computer default stat levels. Computer color changes every 8 levels, computer characters changes every 24 levels. Added a medium and hard lock to  the computer defaults stats table. Created a settings table.
Added a difficulty field to the computer table so when the game resumes we know what difficulty the computer was one. Added a current_computer_level field to the player table so we know what level the player has cleared up to.
