Javaparser: Save filepath/filename in CompilationUnit

[shibumi]

It would be nice if JavaParser.parse(Filename) could return the filepath/filename in the returned Object.

On one hand: this would mean refactoring SourceRoot, on the other hand: this would enable more validations (class matches filename, package declaration wrong, etc.)

At the moment we have an "information leak". When i for example iterate over a big java project and produce CompilationUnits for every file and sort these units into a bigger modell, I would like to have the filepath/filename for every CompilationUnit. I am sure that also other projects would profit from this changes.

Yes, it's probably a good thing and this will be built. In the end it is a design decision, but since our approach is "the Abstract Syntax Christmas Tree" full of decorations, this can go in too.

@matozoid cool awesome!
