Some clean up, mcmod.info file and minor changes.

I've cleaned up some really messy code. I've alsoe noticed that we had 2 or 3 completely unused classes, that we will never use. There was also some outdated methods that weren't deleted.
I have added @SuppressWarning annotations where the warnings weren't important.

I've added an mcmod.info file. I've added a logo image to the request, I think it would be nice to have it.
