umonitor:
Updated copyright date in comment header and startup printf statement.

uedit is now called from umonitor in two places.
Under System Options as:
Run User Editor
This runs uedit as normal
Edit User
This runs uedit directly into edit user mode passing user number on the
commandline and editing the online user directly.  (edtuser gave me the
clue how to do it.)

uedit is called the same way scfg is called.  This requires that uedit
is in the cfg.exec_dir.

I realized that having an edit user function on a node with nobody there
was pretty lame.  Since I wanted Edit User as the first option, I put in
some code to give a "No User Online!" message for now.  I will better
tweak the code later.

I did the same for Spy On Node option with a "Spy On Who?? :)" message.
<g>  Again I will tweak the code to improve this handling.

Added help to most areas.

The menu displayed when hitting enter on a node is now context sensitive
depending on whether or not a user is online.  It makes no sense to Spy
On a node that waiting for a caller :) :)
