I created a simple patch to move the chirp data directory from ~/.chirp to the directory pointed to by $XDG_CONFIG_HOME. It uses ~/.config/chirp as a fallback if $XDG_CONFIG_HOME is not set.

I don't know how to use mercurial, so I've attached the patch here in hopes that someone might help add this to the upstream repo.

This command should apply the patch with no manual intervention: patch -p1 -i chirp-xdgconfig.diff

Thanks, Kian Kasad
