- make it PREFIX, X11BASE and LOCALBASE clean;
- adjust default font, so login.app should work OOB;
- new MASTER_SITE and WWW;
- make GNUstep theme default theme instead of Linux one (it's nasty to see
big `LINUX' letters on FreeBSD login screen ;);
- adjust scripts, so `Restart' and `Power-off' buttons work just OOB.
