Idea: add server-side functionality for better bite detection

[MauveCloud]

I don't really play Minecraft multi-player, so I wouldn't be affected by this, but after reading this part of the readme: "AutoFish bite detection is 100% accurate in Single Player games, where the mod has access to the world server's state. In MultiPlayer games, the mod must rely on the same hints given to players" I realized that for this Forge version of the mod, it doesn't have to be purely client-side. It should technically be possible to add server-side functionality (for any admins willing to install it that way) to overcome the described limitation.
