Remove or increase the 12kb limit on scoreboards

I didn't even know about this limit myself so for the uninformed, if your scoreboard.dat exceeds 12kb it will corrupt and delete itself as Minecraft only allocates that much space for it. This deletes ALL of your teams and scoreboard objectives.

I've been working on a fairly large project and this arbitrary limit has caused me a great amount of bother and I imagine it was imposed when reaching it was unthinkable and was never increased as time went on and scoreboards gained more uses.
