replaced a string comparison for performance and type safety reasons
removed some warnings
added some type information, removed some unused variables, avoided computing stuff over and over again
fix for the fix
interning strings to save memory
interned more strings for performance
1) added a more verbose error message if the directory specified for the Android platform JARs does not exist
2) fixed a potential memory leak. The ZIP file for the APK was never closed again
1) added validation code to make sure that no goto instruction jumps directly to itself as this break the toDex component
2) added a check into toDex to detect self-jumps early on and make debugging easier

related to #148
added classes for determining whether a given invoke expression is fixed, i.e., cannot be overwritten by client code and thus cannot become a callback
corrected computation of fixed methods; now disregarding enclosing types
bugfix against IOException: may not close the jar output stream after writing of the class; instead the stream is closed in the end, through a call to tearDownJAR()

I wonder how this could ever have worked!?
fix for toDex: gracefully handle situation where an instance method does not have a this-local
