Restrictions for free servers: Because we want players
to upgrade the accounts, we have put some limits on
free servers. This includes light effects (seteffect,
setcoloreffect etc.) and complex ganis. 'complex' means
ganis (animations) that are not default animations
and do more than just display an image. Things like
skip.gani are allowed, fishing.gani not.
Using the hat thing is not allowed.
