Added patch from Peter Klauser (klp at users.sf.net), to support
packages with same name as classes in the obfuscator.
* jode/obfuscator/PackageIdentifier.java.in
(loadedPackages): New field, to store packages in separate map.
(getIdentifier): Renamed to...
(getClassIdentifier): ...this (and return only ClassIdentifier).
(setLoadOnDemand): Use loadedPackages.
(loadClass): Likewise.
(loadMatchingClass): Likewise.
(readTable): Likewise.
(getChilds): Likewise.
(contains): Likewise.
