Graal Skills Tournament updates

[Admins]

Several things on the Graal Skills server have been updated, especially for tournaments:

- The game window is bigger, we removed the clouds-header
- The tournament announcement PM leads you directly to the tournament list
- When a tournament is added then a blinking link will appear in the Log window for easily joining the tournament
- When inviting a player to a game then it is automatically selecting the best rule for the selected game (Bombermad: 3 Rounds) to make things easier
- You can bet up to 50 gelats in Poker (might be increased later)
- Nicknames are filtered (some special characters being removed) to avoid problems in multiplayer flash games
- Easier navigation with keyboard: 'Space' starts a game, card games automatically select the first button in the start screen, when closing a game then it is automatically focussing the game list
