- 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
- 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
