better hand to hand combat

Fixed the combat system. When block_and_punch hits a player it no longer goes back to hand. Also you don't spawn with block_and_punch no more. Instead you go into an arena for 32 diamonds - 64 diamonds. If you're team wins you get more diamonds. Loser loses their diamonds. Once game over you go back to where you were last. Also blocking system fixed and tells you if you blocked a attack now.
