BookCrashFixer

As you might know there are many server crasher out there. Most of those have been fixed by other plugins. But not this one. I wanted to make this plugin months ago but never got to it. But now is the time, and I did it.

I hope I can help you with getting your server a bit more secure.

This Plugin needs ProtocolLib as dependency!

For those who don't know how the crasher works:
A player sends a lot of packets to the server containing a large item (a book). The server then loads that item and freezes. That alone would not be that bad but through the spam it can freeze and even crash the server.

This plugin has an easy to use config in which you can set everything for your needs (even a way for players to bypass the check with the correct permission (why am I even doing some stuff?) It is disabled by default, don't worry).
The default config is set for the max possible protection (If you hand your players a book with more chars per page or more pages than possible it may detect them for trying to crash the server). But in default everything should work quite well.
I also hope that server who currently have books disabled because of the crasher can now enable them again without fearing a crash.

Also you are allowed to decompile this plugin and look at the source if you don't trust me.
