Change names of files with the same path - this time by Transformer

Hello,

What about this one? ;)
Ok, thanks for looking at this! WRT variables naming, I was really lost with "archive", it was never clear to me if it is the .jar we are merging into fat jar, or far jar itself.
WRT redundancy, I'll look at this, but AFAIR there was no jar file path in `mergedJar`
