Tweaks for the settings system

- Player settings are located at the group level. Only the first player
that joins the group will be able to configure the settings.
- Default system settings are located at the group of the commend
center. Thus, the COMMANDCENTER class will contain the default system
settings menu. You need to join the command center unit (ALT-J) as a
game master to be able to configure these settings.
