I've been cleaning up the sup configuration files that sup.netbsd.org uses.
The following changes have been made:

* removed 'src/gnu' from the `src' release in the `current' collection

  IMPORTANT NOTE:	the GNU sources were *removed* from the src release
			as they're available as a separate release, and
			consumed a substantial chunk of the src release.


* added ksrc-bebox (BeBox specific kernel files) to the current collection

* added the following releases to the mirror collection:
	1.3		NetBSD 1.3 distribution
	1.3-export	NetBSD 1.3 distribution, sans export controlled files
	arch-bebox	BeBox specific kernel files
	arch-m68k	Kernel files shared between m68k ports
