Cerberus User Paths

This is a configuration to add to the fish PATH. The current version of fish uses a special command called fish_add_path when you want to add locations to the user path. If you just naively append to the PATH in the config file then fish will keep adding to the PATH every time you log in so the fish_add_path prevents adding paths that are already stored in the environment variable. Unfortunately the raspberry PI I'm using has Debian 11 which has fish version 3.1.2 which predates the fish_add_path command so I'll have to add to the path the old fashioned way.

The additions will be in dingehaufen/conf.d/extra_paths.fish which has to be then linked or copied into /.config/fish/conf.d/.
