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.
Just to clarify, the method name where the constant is used is getModContainerCLASS !? 
But I'll have a look why this is needed to be as it is later.
