New nbase-7.0.0.3 release, sysutils/nbase

[cheusov%tut.by@localhost]

Hi folks. I've just released new version of nbase, NetBSD userlevel utilities portable to Linux,
Darwin, OpenBSD and probably other systems.
Pkgsrc package is available in sysutils/nbase.

If any one is interested, please test it and let me know if you find any bug.
