Currently, for caching data, a new directory is created in the current user's home directory. This is bad practice (if all apps just dump files into the user's home, it becomes somewhat unmaintainable). The XDG Basedir Specification covers this pretty neatly; the cache directory for all applications is configurable via the `XDG_CACHE_HOME` variable, and falls back to `~/.cache` if unset. The os.UserCacheDir function returns the per-platorm cache dir, since the XDG-Basedir is *nix-specific (except macOS). This changeset makes the cache for all applications live in one single location, rather that littering the user's home. Co-authored-by: Samuel Karp <[email protected]>
