Attempt to fix nether crash & add config

This is my attempt at fixing the "nether crash". Impossible to test as it's impossible to duplicate the crash. Therefore this is entirely based on our "best guess" of if it'll work.

Also added a new HashMap config.dat file for enabling/disabling patches at will. Very hastily done, not pretty but it works just fine based on my testing. Couldn't use any of the forge helper methods for configs due to the fact that none of those things are loaded yet at ASM time. Is set to create and populate the file with "patchKey" = true if the key is not found when reading the file.

Also added our mod to our transformers exceptions, so we can't patch ourselves while loading ourselves.
