Fixed some errors and made improvements.

- Fixed a bug in loading screen when  there were teams didnt display the
correct penguin on "you".
- Fixed a minor bug with the match time.
- Fixed a bug when the players was defeated the invisible upgrade was
counting down. Now all upgrades are reset when you die.
- Some times when you won you could get killed by an harpoon that were
placed and change the result of the game. Now the player/s that win/s
are invicible and cant get killed.
