#11 Doesn't honor DISPLAY environment variable

[Gary Kramlich]

I have a multihead non xinerama setup, meaning I have 2
displays, a :0.0 and a :0.1. Reguardless of which
screen I run 3ddesk from or even if I run it like this
'DISPLAY=:0.1 3ddesk' it always runs on :0.0. I
haven't taken a look at the code, but with my
experiences with X, I'd guess you're setting it
manually since passing NULL to connect is supposed to
use the environment var if it's there or fallback to :0.0
