fuchsi 5b0c1449e1 various fixes and cleanups for blacklist handling:
1. avoid adding duplicate file name entries in config properties for lists, 
2. correctly merge all path masks from all list files for the same host masks,
3. rewrite helper methods standard java methods for Collection transformations,
4. merged various methods with identical functionality for different Collection implementations into one,
5. minor refactoring to improve code readability.
