[issue730] Latest DEVEL still reflects old pkg_* paths

    If we don't have a working installer by wednesday then
    I will have to take the non-LUA version that we have from the last
    release, bring it into our own CVS, and make it suitable for this
    release.

I put the bsdinstaller under src/contrib, and linked in a `make iso` target to
src/Makefile (it just cds and calls nrelease/ make installer_release -- thanks
Justin).  I also tweaked the nrelease Makefile to build contrib/bsdinstaller
instead of just copying the root skeleton files over.
`make iso` is building now, but I'm not far enough along the process to gauge
its worth (currently at gnu/usr.bin/cc34/ and started ~ 5 hours ago).  
I'm also
not sure if it will finish by Wednesday.  If someone with a quicker build
platform could try the patch below and provide feedback (and hopefully an iso
:-D), I would appreciate.
