Experimental AccessTransformer [DO NOT MERGE]

This is an Experimental AccessTransformer I made (based on the FML one) to change access to methods, fields and classes. the rules for changing the accessMode are in a text file (as I said based on FML).

I just wan't you to see this, maybe this is interesting for BlazeLoader. But this still needs a lot of work.
I made a pull request for this to know if you are interested and I should keep working on it or you're not interested and I should abandon this project.
