Description: Exit when there is no HOME environment variable
 The home directory is used in multiple places without checking
 whether it is non-NULL. I think that it is very unlikely for
 someone to want to use this program without that variable in
 the environment, so we just bail out if it is missing.
 .
 If anyone wants gtk-theme-switch2 to work without a HOME
 environment variable, they will surely file a bug about this.
