Enable file logging by default on desktops to help with troubleshooting 

- Use the `.log` file extension (recognized on Windows out of the box)
  to better hint that generated files are logs. Some editors provide
  dedicated syntax highlighting for those files.
- Use an underscore to separate the basename from the date and
  the date from the time in log filenames. This makes the filename
  easier to read.
- Keep only 5 log files by default to decrease disk usage in case
  messages are spammed.
