I've added fork() to a7out after adding some comments to src/cmd/init.s.

There is a test program to demonstrate fork working.

Phil's change to as7 to implement RELATIVE flag. He says:
...
seems to assemble cat.s and kernel reasonably...
(famous last words)
I've updated a7out to use the same starting location. It runs cat.s OK.

I've updated the top-level Makefile to build all the existing utilities.
...
I've borrowed the V1 manuals from
http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/man/man1
and changed them to reflect the PDP-7 utilities.

another round of (hopeful) improvements
...
add indirect bit to "sys" definition
set initial ".." (output base) to 4096 (not yet honored)
add "ptr" output format (binary in paper tape reader format: 3 frames of 6 bits)
remove IOT instrictions (system source uses sop.s)
always write labels to "n.out"
add debug output
fix multiply defined error handling (process symbolic labels on both passes)
