Solving INT-185, INT-207, INT 201 - refactoring FileSource and FileTarget, splitting AbstractFileMapper in MessageCreator and MessageMapper, adding namespace support for configurable MessageCreator in FileSource and filename generator in FileTarget. Backup directory is not supported anymore, instead FileSource will not delete files and will ignore files already processed.
