Fixed some typos in some files, and I've also made some other changes as well.

I've fixed a bunch of typos in the README, mcmod.info and pack.mcmeta, and I've also made some other changes to the files for easier understanding. 
Actually, yes there is a reason. It makes it easier to understand. I'm sorry, but I am not making any more commits changing this file. I think the changes I made are good. I ain't changing it anymore. Sorry, but I'm not.
