XDG_CURRENT_DESKTOP

[Nick Schermer]

In Xfce XDG_CURRENT_DESKTOP is already used in a number of places as
an override for the default XFCE for {Only,Not}ShowIn. An example can
be found here [1]. The main purpose in our cases are mostly to make
the various parts of Xfce easier to use in other environments.

I think no library should ever assume it runs on a specific desktop,
but only provide the functions for an application to set this (in our
case garcon_set_environment).
