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.
