Support categorized default logging configurations, introduce PID tuning logging configurations

• Support categorized default logging configurations, rather than only a "Default" category.
• Introduce default PID tuning logging configurations. Mainly for plotting reasons.
  • Both in split (e.g. pitch, roll yaw) and combined (e.g. attitude) categories. I found that I was switching between the two depending on how detailed the tuning was. I'm open to other people's opinions on this.

Nice! I don't have anything to object but I have one question, could the spaces in the directories cause any problem?

I used whitespace since our GUI directly displays these names - as far as I know without issues. However, I recognize that whitespace can lead to problems, so to be safe I have replaced them with underscores.

Note that nothing prohibits users from creating folder and file names with whitespace. From the GUI, it may not be immediately apparent that this is directly represented by directories and files. Perhaps this is something to enforce?
