updated package CS2Java

- routine "Java_CopySupportFiles". This routine also returned contents of
".svn" folders --> fixed

- routine "isBaseProcessSuperClass2". Produces an error in case the
"inheritance hierarchy temp file" does not exist - which is the case for
real base classes. --> fixed (fingers crossed).

- the scope of methods is not properly handled (they are all "public") -->
-- Java interface methods are always implicitly public, sorry!
-- as a workaround I have implemented an option that prevents generation of
Java code for private methods.

- version number set to 1.03 (SCC 6522)
