Created new file named Global.Java

+ Created new file Global.java
* Extracted most String Literals from across the project into one file.

-- I just think it would be easier to consolidate all commonly used Literals to one file, to increase efforts.
Because this is in the FML loading plugin, if you cause the class to be looked up in the parent classloader (which using the class literal *will*) then bad things will happen. These entries are strings for a damn good reason and you can't just change them to class literals without creating a chicken/egg sitatuation.
