[STUMP] Patch for setting of DISPLAY-variable.

[Troels Henriksen]

When I hack on Stumpwm, I usually run it from a Lisp that runs inside
Emacs inside an X-seesion. That means that Stumpwm inherits the
environment-variable settings from Emacs, which causes applications
started through Stumpwm to pop up on the same display that I'm running
Emacs in. Since I run Stumpwm on a different display (commonly :1, as
opposed to the :0 that hosts Emacs), this is really annoying. Attached
is a patch to stumpwm.lisp that will set the
DISPLAY-environment-variable properly when Stumpwm starts.
