Crash when Witchery jar name is lowercase on case-sensitive file systems

[Roadhog360]

I am running a Linux system with Ubunutu. Earlier this year my friend and I were pulling our hair out over a crash we thought was just Witchery, I don't remember the whole detail because it was a while ago, but somehow we ruled out WitcheryExtras even though it was the cause.

Today we tried again and found out something peculiar. So, it turns out this mod will crash on a file system with case-sensitivity like Linux with Ubuntu if the Witchery file name is lowercase.

The old jar name was witchery-1.7.10-0.24.1.jar, renaming it to Witchery-1.7.10-0.24.1.jar works and fixed this crash, which does not happen when WitcheryExtras is installed.
