Fish are changed in disabled worlds

[thomas-worm]

Hello,

while fishing in a world disabled by contest-disabled-worlds the fish were converted into contest fish. The player thinks he is part of the contest but he isn't.

So it would be great if one of the two following alternatives can be implemented:

1. Warn the player with a message that he is in a world in which he cannot be part of the contest.
2. Leave fish as is in these worlds.

Thanks and best Regards,
Thomas

I added a config option named disabled-worlds for disabling the replacement of the fish in these worlds. I will send you a pull request for that.
