Remove debug logs
DBG
is defined under #if DEBUG ...
in libxfce4util/xfce-debug.h
and somehow this is defined, at least in the official OpenBSD package
build.
Those state change logs keeps spamming my ~/.xsession-errors
file and
I doubt they are really useful to the average user.
Anyone debugging/hacking wavelan will check the code anyway, so rather
than diggin where and why DEBUG
gets defined, remove the logs.
