[catmod fs] Bring in-line with XDG Base Directory Specification

Describe the current state of the problem Currently, by default, the “Desktop’s file system” catmod uses ~/${author_name}/${project_name} which has the potential to heavily pollute the user’s home directory when ct.js becomes more popular.

Describe the solution you’d like Instead it should follow the XDG Base Directory Specification, which states the following locations should be used for various purposes.

$XDG_DATA_HOME as the base directory for data files. Defaults to ~/.local/share $XDG_CONFIG_HOME as the location for configuration files. Defaults to ~/.config

This part is more subjective, but I do not think the author’s name should be used in the path. Instead a separate “Organization Name” should be created and used in it’s place. It’s conceivable that in some organizations, there is not one specific author, but for indie development, I believe a lot of people would have the two be separate.

For an example. If I published a game called Vroom under a Organization called Ursid I would expect the data and config directories to likely be as follows: ~/.local/share/ursid/vroom/ ~/.config/ursid/vroom/

Describe alternatives you’ve considered (optional) I do not think that there is any good alternative to using the specification, however I can see the separation of author and organization being rejected. However if it does, I would suggest renaming it to “developer name”.

Additional context I have no idea if MacOS follows the specification and I would be surprised if Windows did. This is mainly for Linux.

I may have accidentally broken my branch with git. I’ll need to fix it before PR

Edit: Nope, I just forgot which branch I was using.

I can test on windows and Mac.
