More options for config location, e.g. XDG_CONFIG_HOME

[Destroy666x]

Would be nice if more standard locations such as XDG_CONFIG_HOME (on all systems) or %APPDATA% (on Windows} were supported for easier cross-system configuration. Currently as I see only home dir is supported:

vt-cli/cmd/init.go

dir, err := homedir.Dir()
