Moved opr.s to src/other as it is not a proper utility and wasn't in the scans.

as.s starting to work! Add ops.s

replaced "sys write; 1; 0; 4" with "sys write; 1: 0; 4"
In the scan it REALLY looks like three semis, but that makes NO sense!

the definitions of . and .. from wktopr.s, I can now assemble cat.s with

I added smes and rmes system calls to a7out and wrote some code
...
in src/other/fork_test.s to test it. It's not working quite right
yet, we keep getting wait() returning -1 in a7out even though there
is a child process.
