initctl list output...

[David Jeske]

I didn't see any replies to my comments about the ui/output of "initctl
list"... after some experimentation in the code, you can see what I came up
with below.

1) I don't have any examples of multi-process services, so I edited the
output to add a "fake" second process for rsyslog so you can see what it
would look like.

2) the "xx:xx" is intended to be the length the process has been running.
I'm working on filling in the real numbers now..

3) I'm thinking of adding a command/flag for a "machine readable" version
of "list"... (the current list isn't very machine readable, but this format
is less so)

4) I'm thinking about sorting this output, probably by prop-name....

Thoughts?
