- Remove TaskOption and central logic for processing options. It is not flexible and clear enough without investing a lot of effort. Fix is easy - just pass the scanner and let the task do what it needs to do.
- Permissions: Do not write to generated file without explicit consent by user (default behavior of runners should be _not_ to do any I/O)
- Fix wrong check in messages; minor output adjustment
- Remove hacky check to see if last char of a file is a new line
- Add messages with new line to same line with &n
- Add German translation for missing key
- Adjust messages filename pattern to include Chinese files (with 4-letter codes)
- Change verifier to only output errors (more "to-the-point" output)
- Close scanner for all cases
- Replace read from file with the one from the File service
- Rename file service class to FileUtils to better reflect its purpose
