- Add new methods temporarily to NewEncrMethod interface
- No data source access within EncryptionMethod implementations
- Generate the salt within the EncryptionMethod implementation
- Deprecate static methods on PasswordSecurity
- Adjust AbstractEncryptionMethodTest to test the classes with the new interface
- Add getter for data source instead of accessing field directly
- Abstract Messages into two layers: the top layer 'Messages' is how Messages can be retrieved and sent as before. In the background, package-private, MessagesManager actually does the file read and worries about I/O while Messages takes care of higher-level things (such as joining two lines or checking the current language).
