draklive: allow installer GUI to be used and run as normal user.
Read all configuration from the main config file and automatically generate the auto_inst.cfg.pl file. Run the installer GUI in a nested X server if any items are not specified in the config file. Use sudo to run any steps that need root privileges, to avoid running the X server as root.
