- Added checks for missing arguments.
- Fixed some weird bugs

Fixed some bugs.
Also, modes are planned to be added in some version, so added the support for them. There's no logic for them yet, but you need to choose the mode when starting a new biathlon game.
Have fun!

Yeah, BiaMine now has autocomplete on every command, that might need it!
Have fun.

Fixed Bugs
- /exclude command not showing error messages
- Error messages for /exclude having wrong color.

Added permissions for easier usage!

Yeah, I also thought that including everyone in the game, without them even knowing that is kinda annoying.
Well, now you can fix that!

Using /exclude you can exclude whoever you want from whatever game you have!

Usages:
/exclude <gameID> <player> [add -r to remove]
> Adds or removes the player to selected game's exclusions.
Example1: /exclude biathlon1 Notch > add Notch to exclusion list of game biathlon1
Example2: /exclude biathlon1 Notch -r > remove Notch from the exclusion list of game biathlon1

/exclude <gameID> view
> Prints out the list of excluded players for that game.

/exclude <gameID> clear
> Clears the exclusion list for that game.

A major bug has been fixed, that made the stopwatch dependant of player count. This does not occur anymore.
