GIS.sh update again

[Markus Neteler]

Hi,

some people reported a DISPLAY-variable problem. I have
added the specific line to the bash part of GIS.sh.
Store this file to

grass4x/etc/GIS.sh

You need, even if you have a stand-alone machine, to configure
your network to "local loopback" or similar. It must be configured
into working condition.

Hope this helps

Markus
